Question

Chelsea drew two parallel lines KL and MN intersected by a transversal PQ, as shown below.
Which fact would help Chelsea prove that the measure of angle KRP is equal to the measure of angle MSR? (1 point)
Question 2 options:
1)When angles KRS and MSR are equal to angle RSN, the angles KRP and MSR are congruent.
2)When angles KRP and KRS are equal to angle LRS, the angles KRP and MSR are congruent.
3)When angle LRS is equal to angle KRP and angles LRS and RSN are complementary, angle KRP and angle MSR are congruent.
4)When angle LRS is equal to both the angles KRP and MSR, angle KRP
