How is geometry used in everyday life? When you’re studying a subject‚ the science of lines and angles can seem like nothing more than a dull exercise in formulas and predictability. In reality‚ geometry is at work everywhere you go. Whether you’re aware of it or not‚ geometry quite literally shapes our lives. An Ancient Science‚ how long has geometry been around? To answer that question‚ let’s take a look at where geometry gets its name. Geometry is derived from the Greek words for Earth (Geo)

is not a problem! Geometry (Ancient Greek: γεωμετρία; geo- "earth"‚ -metri "measurement") "Earth-measuring" is a branch of mathematics concerned with questions of shape‚ size‚ relative position of figures‚ and the properties of space. Geometry is one of the oldest mathematical sciences. Initially a body of practical knowledge concerning lengths‚ areas‚ and volumes‚ in the 3rd century BC geometry was put into an axiomatic form by Euclid‚ whose treatment—Euclidean geometry—set a standard for many

Geometry (Ancient Greek: γεωμετρία; geo- "earth"‚ -metron "measurement") is a branch of mathematics concerned with questions of shape‚ size‚ relative position of figures‚ and the properties of space. A mathematician who works in the field of geometry is called a geometer. Geometry arose independently in a number of early cultures as a body of practical knowledge concerning lengths‚ areas‚ and volumes‚ with elements of a formal mathematical science emerging in the West as early as Thales (6th Century

Non-Euclidean geometry is any form of geometry that is based on axioms‚ or postulates‚ different from those of Euclidean geometry. These geometries were developed by mathematicians to find a way to prove Euclid’s fifth postulate as a theorem using his other four postulates. They were not accepted until around the nineteenth century. These geometries are based on a curved plane‚ whether it is elliptic or hyperbolic. There are no parallel lines in non-Euclidean geometry‚ and the angles of triangles

Elliptic geometry (sometimes known as Riemannian geometry) is a non-Euclidean geometry‚ in which‚ given a line L and a point p outside L‚ there exists no line parallel to L passing through p. Elliptic geometry‚ like hyperbolic geometry‚ violates Euclid’s parallel postulate‚ which asserts that there is exactly one line parallel to L passing through p. In elliptic geometry‚ there are no parallel lines at all. Elliptic geometry has other unusual properties. For example‚ the sum of the angles of any

Geometry divided into two types such as plane geometry and solid geometry. Plane Geometry is about flat shapes like lines‚ circles and triangles. shapes that can be drawn on a flat surface called a Plane (it is like on an endless piece of paper). Solid Geometry is about solid (3-dimensional) shapes like spheres and cubes. Geometry topics taught in high school or secondary

NTRODUCTION: Geometry is used to know about all kinds of shapes and their properties in our daily life problems. Plane geometry - It is about all kinds of two dimensional shapes such as lines‚ circles and triangles. Solid geometry - It is about all kinds of three dimensional shapes like polygons‚ prisms‚ pyramids‚ sphere‚ cylinder. The word Geometry comes from Greek which means earth and metron.
