Pythagoras' famous theorem for right-angled triangles c2 = a2 + b2 can be visualized in this diagram. The area of the blue square = c x c = c2. Similarly for b x b, a x a and the red and green squares. Therefore area of blue square = area of green square + area of red square c = . a = . b = . c2 = . a2 = . b2 = . . . .
