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

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

45
