"WebPythagoras' Theorem. Let's start with a quick refresher of the famous Pythagoras' Theorem. Pythagoras' Theorem says that, in a right angled triangle: the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). a 2 + b 2 = c 2. That means we can draw squares on each side: And this will be true: A + B = C " - Circle theorem semi circle
