Which statement explains the Pythagorean Theorem? (1 point) If a triangle is a right triangle, then the sum of the squares of the legs is equal to the square of the hypotenuse. If a triangle is a right triangle, then the sum of the squares of the longest leg and the hypotenuse is equal to the square of the third sides If the interior angles of a triangle add up to 180 deg then the sum of the legs of the triangle is equal to the square of the hypotenuse. If all angles in a triangle are of equal measure, then the length of all sides will be equal.
