Basi began her proof of the Pythagorean Theorem with a right triangle and drew an altitude from the vertex opposite the hypotenuse to the hypotenuse. This gave her three right triangles—the original and two smaller triangles that the original was divided into. If the legs of the original measured 8 cm and 15 cm, which of these is the length of the hypotenuse of one of the three right triangles? Select three that apply.
