Thales and the Great Pyramid of Giza Thales played an important part in Geometry. On his studying in Egypt, he had discovered many theorems. One of these theorems included finding the height of a pyramid. It was very astonishing for him to do this because he had no supply of modern tools. Because of his discoveries, Thales is now known as "the father of geometry." Thales was born in Greek Ionia in 622 B.C. He …showed first 75 words of 494 total…

…showed last 75 words of 494 total…with an object of known height. While doing this, Thales discovered a theorem in geometry. It states that if two triangles have two corresponding angles congruent, and two corresponding sides congruent, then the remaining angles and sides are congruent. From this, Thales introduced the concept of ratio. In conclusion, Thales was a great mathematician who played an important role in the growth of geometry. He was known as a person who can do the impossible.
