Which of the following reasons completes the proof in the picture?
A.a bisect or divides a segment into two congruent segments
B.perpendicular segments form angles of equal measure
C.perpendicular bisect ours form congruent right angles
D.symmetric property
The correct answer here is A because it asks to prove congruence. Since we know line ST is the BISECTOR of PR, we know that Q is the middle point and indeed PQ and RQ are congruent lines.
