Pythagoras' states: . If we want to obtain the hypotenuse, c, we need to take squares on both sides. It's just inherent in the definition of the hypotenuse:
Good day! Im a noob in math so i just want to ask this simple question. I know that Pythagorean theorem is the sum of the areas of 2 squares on the legs equals to the area of the square on the hypotenuse. My question is; why did they refer to a square to prove the a theorem that is being used into a triangle? thanks in advance.
