Mathematicians sometimes use the term to encompass higher dimensional geometries with similar properties. But the reason why Euclid is considered to be the father of geometry, and why we often talk about Euclidean geometry, is around 300 BC-- and this right over here is a picture of Euclid painted by Raphael. In this chapter, we shall discuss Euclid’s approach to geometry and shall try to link it with the present day geometry. In Euclidean geometry these are one and the same thing. The system of axioms of Euclidean geometry is based on the following basic concepts: point, line, plane, motion, and the relations “a point lies on a line in a plane” and “a point lies between two other points. Solution. This subject is based on a number of definitions such as point and line together with a number of postulates about geometric properties.
