What is the difference between the pythagorean theorem and its converse?

a. the pythagorean theorem states that the sum of the squares of the two shortest sides of a right triangle equals the square of the longest side. the converse of the pythagorean theorem states that the sum of the squares of the two shortest sides of a triangle that is not a right triangle does not equal the square of the longest side.
b. the pythagorean theorem states that the sum of the two shortest sides of a right triangle equals the square of the longest side. the converse of the pythagorean theorem states that the sum of the two shortest sides of a triangle that is not a right triangle does not equal the square of the longest side.
c. the pythagorean theorem states that the sum of the squares of the two shortest sides of a right triangle equals the square of the longest side. the converse of the pythagorean theorem states that if the sum of the squares of the two shortest sides of a triangle equals the square of the longest side, then the triangle is a right triangle.
