The Most Famous Document of Babylonian Mathematics: Plimpton 322. Plimpton 322 reveals that the Babylonians discovered a method of finding Pythagorean triples, that is, sets of three whole numbers such that the square of one of them is the sum of the squares of the other two.
Pythagoras' Theorem Years ago, a man named Pythagoras found an amazing fact about triangles: If the triangle had a right angle (90°) ... ... and you made a square on each of the three sides, then ... ... the biggest square had the exact same area as the other two squares put together!
A Pinner said: A visual proof of the Pythagorean Theorem. When I taught this in class, I had the students prove it themselves by cutting out squares on graph paper. They cut out the square of side A and the square of side B, and then they pasted the squares along the hypotenuse. They loved it! - I MUST TRY THIS!!!
