Little is know about Euclid, the father of geometry. Records show that he lived somewhere around 300 B.C. He was a Greek mathematician and is probably best known for his work Elements. Since little is known about the personal life of Euclid, it is difficult to do a biography on him.

His chief work, entitled Elements, is a comprehensive essay on mathematics. It includes 13 volumes that entail such subjects as plane geometry, dealing with the properties of flat surfaces and of planar figures, such as the triangle; proportion in general, a particular kind of relation between groups of numbers or quantities; the properties of numbers; incommensurable magnitudes; and solid geometry, branch of geometry that deals with the properties and measurement of geometric figures in three-dimensional space. Some people say that the geometrical sections of Elements were actually rearrangements of Exodus previous work. However Euclid himself is said to have made several discoveries in his Number Theory, which is a branch of mathematics that deals with the properties and relationships of numbers.

Most historians believe Euclid was educated at Athens. His teachers may have included pupils of Plato, who was a philosopher and one of the most influential thinkers in Western philosophy. Euclid thought geometry in Alexandria and opened a school of mathematics there. He also wrote Data, which was a collection of geometrical theorems; Phenomena, a description of the heavens; and The Division of the Scale, which is a mathematical discussion of music. But yet again many historians believe many of these works (other than the Elements) were spuriously credited to him, others disagree and say that indeed his works are that of his own.

Euclid's Elements was used as a text for 2000 years, and even today a modified version of its first few books forms the basis of high school instruction in plane geometry. The first printed edition of Euclid's works was a translation from...

...HISTORY OF MATHEMATICS
The history of mathematics is nearly as old as humanity itself. Since antiquity, mathematics has been fundamental to advances in science, engineering, and philosophy. It has evolved from simple counting, measurement and calculation, and the systematic study of the shapes and motions of physical objects, through the application of abstraction, imagination and logic, to the broad, complex and often abstract discipline we know today.
From the notched bones of early man to the mathematical advances brought about by settled agriculture in Mesopotamia and Egypt and the revolutionary developments of ancient Greece and its Hellenistic empire, the story of mathematics is a long and impressive one.
Prehistoric Mathematics
The oldest known possibly mathematical object is the Lebombo bone, discovered in the Lebombo mountains of Swaziland and dated to approximately 35,000 BC. It consists of 29 distinct notches cut into a baboon's fibula. Also prehistoric artifacts discovered in Africa and France, dated between 35,000 and 20,000 years old, suggest early attempts to quantify time.
The Ishango bone, found near the headwaters of the Nile river (northeastern Congo), may be as much as 20,000 years old and consists of a series of tally marks carved in three columns running the length of the bone. Common interpretations are that the Ishango bone shows either the earliest known...

...History of mathematics
A proof from Euclid's Elements, widely considered the most influential textbook of all time.[1]
The area of study known as the history of mathematics is primarily an investigation into the origin of discoveries in mathematics and, to a lesser extent, an investigation into the mathematical methods and notation of the past.
Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. The most ancient mathematical texts available arePlimpton 322 (Babylonian mathematics c. 1900 BC),[2] the Rhind Mathematical Papyrus (Egyptian mathematics c. 2000-1800 BC)[3] and the Moscow Mathematical Papyrus (Egyptian mathematics c. 1890 BC). All of these texts concern the so-calledPythagorean theorem, which seems to be the most ancient and widespread mathematical development after basic arithmetic and geometry.
The study of mathematics as a subject in its own right begins in the 6th century BC with the Pythagoreans, who coined the term "mathematics" from the ancient Greekμάθημα (mathema), meaning "subject of instruction".[4]Greek mathematics greatly refined the methods (especially through the introduction of deductive reasoning andmathematical rigor in proofs) and expanded the subject matter of mathematics.[5] Chinese...

...Geometry was throughly organized in about 300 B.C, when the Greek mathematician, Euclid gathered what was known at the time; added original book of his ownand arranged 465 propositions into 13 books called Elements.
Geometry is the mathematics of space and shape, which is the basis of all things that exist. Understanding geometry is necessary step by understanding how the things in our world exist. The applications ofgeometry in real life are not always evident to teenagers, but the reality is geometry infiltratesevery facet of our daily living.
Geometry was recognized to be not just for mathematicians. Anyone can benefit from the basic learning of geometry, which is to follow the lines reasoning. Geometry is one of the oldest sciences and is corcerned with questions of shape, size and relative position of figures and with properties of space.
Geometry is considered an important field pf study because of its applications in daily life.
Geometry is mainly divided in to two which is planegeometry and solid geometry. Planegeometry is about all kinds of two dimensional shapes such as lines, circles, and triangles. While Solid geometry is about all kinds of three dimensional shapes like polygons, prisms, pyramids, sphere and...

...one thing I focus on is “do I understand the material we covered today?” This will allow the material to build itself up in my head, and I will be less stressed come test time.
Research
For my research topic, I wanted to study Isaac Newton. But Mr. Corby wouldn’t let me do this. So I was given a less cool mathematician, Euclid.
Euclid was a Greek mathematician, and was often considered the “father of geometry.” He was born around 330 BC, and he got his training at Plato’s Academy in Athens. He taught mathematics at the Library of Alexandria in Alexandria, Egypt. His most celebrated accomplishment was his drafting of Elements, a volume of 13 works that compiled general geometric knowledge.
Some of the most basic theorems in Elements are: “a point is that which has no part”, “a line is a breadthless (without width) length”, ”the ends of a line are points”, and “a surface is that which has length and breadth (width) only.” All of these definitions appear in the first of 13 books. There are over 150 definitions in these volumes, dealing with both plane and spatial geometry.
Nearly all of these definitions and propositions are still agreed upon the world over, and they are used as tools to teach students the properties of geometric figures.
One of the most important postulates Euclid drafted was the “Pythagorean Theorem”, a relation between the side lengths of right triangles. This theorem is one of the many...

Introduction
"Geometry," meaning "measuring the earth," is the branch of math that has to do with spatial relationships. In other words, geometry is a type of math used to measure things that are impossible to measure with devices. For example, no one has been able take a tape measure around the earth, yet we are pretty confident that the circumference of the planet at the equator is 40,075.036 kilometres (24,901.473 miles) . How do we know that? The first known case of calculating the distance around the earth was done by Eratosthenes around 240 BCE. What tools do you think current scientists might use to measure the size of planets? The answer is geometry.
However, geometry is more than measuring the size of objects. If you were to ask someone who had taken geometry in high school what it is that s/he remembers, the answer would most likely be "proofs." (If you were to ask him/her what it is that s/he liked the least, the answer would probably be "proofs.") A study of Geometry does not have to include proofs. Proofs are not unique to Geometry. Proofs could have been done in Algebra or delayed until Calculus. The reason that High School Geometry almost always spends a lot of time with proofs is that the first great Geometry textbook, "The Elements," was written exclusively with proofs....

...Euclidean GeometryGeometry was thoroughly organized in about 300 BC, when the Greek
mathematician Euclid gathered what was known at the time, added original work of
his own, and arranged 465 propositions into 13 books, called 'Elements'. The
books covered not only plane and solid geometry but also much of what is now
known as algebra, trigonometry, and advanced arithmetic.
Through the ages, the propositions have been rearranged, and many of the
proofs are different, but the basic idea presented in the 'Elements' has not
changed. In the work facts are not just cataloged but are developed in a
fashionable way.
Even in 300 BC, geometry was recognized to be not just for
mathematicians. Anyone can benefit from the basic learning of geometry, which
are how to follow lines of reasoning, how to say precisely what is intended, and
especially how to prove basic concepts by following these lines of reasoning.
Taking a course in geometry is beneficial for all students, who will find that
learning to reason and prove convincingly is necessary for every profession. It
is true that not everyone must prove things, but everyone is exposed to proof.
Politicians, advertisers, and many other people try to offer convincing
arguments. Anyone who cannot tell a good proof from a bad one may easily be
persuaded in the wrong direction. Geometry provides a simplified universe,...

...“Father of Geometry”
Euclid is a Greek mathematician. He was also known as Euclid of Alexandria, “The Father of Geometry”. Little is known of his life other than the fact that he taught at Alexandria, being associated with the school that grew up there in the late 4th century B.C. It is believed that he taught at Plato's academy in Athens, Greece. Most history states that he was a kind, patient, and fair man. One story that exposes something of his personality, involves a student that has just finished his first geometry lesson. The pupil asked what he would gain from learning geometry. Euclid told his slave to get the student a coin so he would be gaining from his studies. Another story says that Ptomlemy asked Euclid if there was an easier way to learn geometry, the mathematician responded, "there is no royal road to geometry", and sent the king to study. Euclid wrote many books such as Data, On Divisions of Figures, Phaenomena, Optics, the lost books Conics and Porisms. He is famous for his Elements, presented in thirteen books of the geometry and other mathematics known in his day. The first six books involve elementary planegeometry and have served as the basis for most beginning courses on this subject. The other books of the Elements take care of the theory of numbers and certain problems in math (on a...

...The evolution of mathematics might be seen as an ever-increasing series of abstractions, or alternatively an expansion of subject matter. The first abstraction, which is shared by many animals,[19] was probably that of numbers: the realization that a collection of two apples and a collection of two oranges (for example) have something in common, namely quantity of their members.Evidenced by tallies found on bone, in addition to recognizing how to count physical objects, prehistoric peoples may have also recognized how to count abstract quantities, like time – days, seasons, years.[20]
More complex mathematics did not appear until around 3000 BC, when the Babylonians and Egyptians began using arithmetic, algebra and geometry for taxation and other financial calculations, for building and construction, and for astronomy.[21] The earliest uses of mathematics were in trading, land measurement, painting and weaving patterns and the recording of time.
In Babylonian mathematics elementary arithmetic (addition, subtraction, multiplication and division) first appears in the archaeological record. Numeracy pre-dated writing and numeral systems have been many and diverse, with the first known written numerals created by Egyptians in Middle Kingdom texts such as the Rhind Mathematical Papyrus.[citation needed]
Between 600 and 300 BC the Ancient Greeks began a systematic study of mathematics in...
