Pythagorean Theorem

The Pythagorean Theorem states that the square of the hypotenuse of a
right triangle is the sum of the squares of the legs, that is, c2 = a2 + b2, as shown in the animation.
How can this be proved? By creating three more identical triangles and rotating them 90°, 180°, 270° clockwise, respectively, we form a square with sides of length (a+b). |

| The
area of this newly formed square is equal to the sum of the areas of
the four right triangles and the square in the center. Expressing this
algebraically, we have:
By simplifying this equation, we obtain:
