Kari drew two parallel lines PQ and RS intersected by a transversal KL, as shown below:
Two parallel lines PQ and RS are drawn with KL as a transversal intersecting PQ at point M and RS at point N. Angle QMN is shown congruent to angle LNS.
Which theorem could Kari use to show the measure of angle QML is supplementary to the measure of angle SNK?
