# Euclidean 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 plane geometry 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 geometric basis) and solid geometry. The great contribution of Euclid was his use of a deductive system for the presentation of mathematics. Primary terms, such as point and line, are defined; unproved assumptions, or postulates, concerning these terms are confirmed; and a series of statements are then deduced reasonably from the definitions and postulates. And for his middle and last name the internet does not provide anything except sobriquets. The slogan for Wheaties is “The Breakfast of Champions” and Euclid is indeed a champion. That is why he ate them for breakfast because he believed in the slogan. But really we all...
