Line k is the perpendicular bisector of (line)pq. if line k intersects (line)pq at point r, which of the following statements must be true?
check all that apply
a. line k bisects pq
b. pr is congruent to qr
c. line k intersects pq at a 90 angle
d. point r is the midpoint of line k
e. line k is parallel to pq

A. Line k bisects PQ

B. PR is congruent to QR

C. Line k intersects PQ at a 90 angle

Step-by-step explanation:

A perpendicular bisector of a line is a segment that cuts right in the middle a line, and that segment forms a 90º degree angle with the line. This means that the point where the segment cuts the line would be exactly the half, making both resultant segments on the line congruent. So the options that are correct are ABC.
