To prove the Pythagorean Theorem, Justin began with a right triangle and drew an altitude from the vertex opposite the hypotenuse to the hypotenuse. This resulted in the original triangle being divided into two smaller triangles. Which of these facts will allow Justin to finish his proof?
A One of the smaller triangles is congruent to the original triangle, and one is not.
B
Both of the smaller triangles are congruent to the original triangle.
One of the smaller triangles is similar to the original triangle, and one is not.
D
Both of the smaller triangles are similar to the original triangle.
