This creates the following three similar triangles. AA Q Using the first two triangles, the proportion, or a² = cd, is true. Using the first and third triangles, the proportion, or b² = ce, is true. Therefore, a² + b² = cd + ce = c(d+e). But because d + e = c, it follows that a² + b² = 2² For the proof to be correct, which of the following statements about line segment QS must be true? A B C It must bisect angle PQR. It must be congruent to line segment QR. It must bisect the hypotenuse of triangle PQR. D It must be perpendicular to the hypotenuse of triangle PQR b d

Using the first two triangles, the proportion = 4, or a? = cd, is true. Using the first and third triangles, the proportion= 5, or b? = ce, is true. Therefore, a? + b = cd + ce = c(d + e). But because d +e = c, it follows that a? + 6? = 2.
For the proof to be correct, which of the following statements about line segment QS must be true?
It must bisect angle PQR.
B
It must be congruent to line segment QR.
It must bisect the hypotenuse of triangle PQR
