...c as shown, then c2 = a2 + b2 [Triangle graph drawn with coordinates] On the left, we have a big square which has side length a + b and so its area is (a +b)(a +b) Depending on how long it is since you have had to do algebra, I can ensure you that: (a +b)(a +b) = a2 + b2 + 2ab But we also know the area of the little square and the triangles. Each triangle is ½ ab. We...
