Pythagorean Theorem
Square root property
The Pythagorean Theorem The sum of the squares of the lengths of the legs of a right triangle equals the square of the length of the hypotenuse. If the legs have lengths a and b, and the hypotenuse has length c, then a² + b² = c². Hypotenuse A b Leg B a Leg C
