Kari drew two parallel lines pq and rs intersected by a transversal kl, as shown below: which fact would kari prove that the measure of angle qmn is equal to the measure of angle snl? a. interior angles mnr and pmn are congruent to each other, and vertical angles snl and mnr are congruent to each other. b. alternate interior angles mnr and qmn are congruent to each other, and vertical angles snl and mnr are congruent to each other. c. alternate interior angles mns and pmn are supplementary and vertical angles snk and rnl are congruent to each other. d. interior angles mnr and pmn are supplementary and consecutive angles snl and mns are congruent to each other.
