Geometry was used as an explanation for the properties of shapes in the world around us. Geometry was first discovered by a man named Thales of Miletus. Thales was the first person to be credited in the history of mathematics (According to James Lightner, 2001). After Thales there was Pythagoras who created the pythagorean theorem. Following Pythagoras was Euclid, who wrote a book called The Elements which included several theorems now widely accepted. Geometry itself was made by taking real world properties and shapes and turning them into formulas to explain why shapes act the way they do.

Geometry’s first impact on civilization was its usage of proof. Geometry was one of the first systems widely accepted that was able to back itself up. Civilizations during this time period used to blame everything on the will of their respective gods (As said by Vassilis Karasmanis, 2000). Geometry was one of the first tools to need evidence to back up the claims being made. Now, showing work is mandatory in almost any math class, especially geometry.
