Which Best summarizes the Pythagorean theorem

the sum of the squares of the lengths of the legs of a right triangle equal the square of the length of the hypotenuse
Explanation
Pythagorean theorem is related to the right angle triangle and it states that
c^2= a^2 + b^2
Where C is the length of the hypotenuse
a and b are the length of the sides of the triangle
The theorem states that the sum of the squares of the lengths of the sides of a right triangle is equal to the square of the length of the hypotenuse
