The figure below shows PQ and RS as parallel lines cut by the transversal XY. Which fact is used to prove that angles QMN and MNR are congruent?
Parallell lines yield congruent alternate interior angles
If a transversal intersects two parallel lines, the alternate interior angles are equal. If two parallel lines are cut by a transversal, the sum of the complementary angles is 180˚. If a transversal intersects two parallel lines, the vertical angles are supplementary. If two parallel lines are cut by a transversal, the sum of the alternate exterior angles 180˚.
If a transversal intersects two parallel lines, the alternate interior angles are equal.
how?
Its just the way life works yo
i guessed that answer anyways so thanks! : )

If you make a triangle out of the transversal, the 2 triangles will be congruent. Therefore triangle corresponding angles A and B will be congruent
ya i understand thanks
