Which example describes Pythagorean theorem?

Question

Which of the following correctly describes the Pythagorean theorem?

1. A.The product of the squares of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse.
2. B.The product of the lengths of the legs of a right triangle is equal to the length of the hypotenuse.
3. C.The sum of the lengths of the legs of a right triangle is equal to the length of the hypotenuse.
4. D.The sum of the squares of the lengths of the legs of a right triangle is equal to the square of the length of the hypotenuse.

Answer 1

four is correct

hypotenuse squared = sum of squares of the other 2 sides

It's like the distance formula: d^2 = x^2 + y^2, h^2 = b^2 + h^2. the hypotenuse or longest side of a right triangle squared = the sum of the squares of the base and height of the right triangle.
