Pythagoras is known for developing the Pythagorean Theorem. This theorem is a formula that helps people to measure the relationship between the sides of a right triangle.
Euclid, on the other hand, wrote Elements, one of the most significant mathematics textbooks. This book discusses several topics including proofs and Euclidean geometry.
Euclid wrote thirteen books of mathematics that have postulates, definitions, theorems and constructions, and mathematical proofs of the propositions mentioned. It is considered the most influencial textbook ever written in history.
Pythagoras came up with what is now called the Pythagorean Theorem (also known as "the Pythagoras' Theorem). This theorem is a fundamental relation among the three sides of a right triangle in Euclidean geometry.
