Pythagorean Theorem
The Pythagorean Theorem is given as  where  is the length of the hypotenuse of a right triangle and  and  are the lengths of the legs. *Click Show Side Lengths*. We can think of  as the area of the square created from that side. The same goes for  and . *Click Show Squares*. The Pythagorean Theorem states that if we add the areas of the leg squares it will always equal the area of the hypotenuse square. *Click Show Calculations*. Move the A and B vertices to change the triangle and verify that  is always equal to .
