For a right triangle, the square of the hypotenuse length [b]c[/b] equals the sum of the squares [br]of the leg lengths [b]a[/b] and [b]b[/b].

The area [b]c[sup]2[/sup][/b] of the big square transforms into the sum[br]sum [b]a[sup]2[/sup] + b[sup]2[/sup][/b] of the areas of the two smaller squares.
