Question

answer attempt 1 out of 2
qr is a segment bisector.
qr is a perpendicular bisector.
qr is an angle bisector.
q is the vertex of a right angle.
r is the vertex of a right angle.
r is the mid - point of a segment in the diagram.

Explanation:

A segment bisector divides a segment into two equal - length parts. A perpendicular bisector is a segment bisector that is also perpendicular to the segment. An angle bisector divides an angle into two equal - measure angles. In the given diagram, since there is no indication of perpendicularity or angle - dividing properties related to \(QR\), and we see that \(PQ = QM\), \(QR\) divides the segment \(PM\) into two equal parts. So \(QR\) is a segment bisector.

Answer:

QR is a segment bisector.
