   1. If two lines are cut by a transversal so that alternate interior angles are (congruent, supplementary, complementary), then the lines are parallel. 2. If two lines are cut by a transversal so that same-side interior angles are (congruent, supplementary, complementary), then the lines are parallel. 3. If two lines are cut by a transversal so ...

   Proofs and Postulates: Triangles and Angles Parallel Line Postulate: If 2 parallel lines are cut by a transversal, then their coresponding angles are congruent. A simple sketch can show the parallel line postulate. note: moving each point the same distance and direction will produce a parallel line (and a coresponding angle)
