Use this worksheet to investigate angle relationships formed when two non-parallel lines are cut by a transversal.

If two non-parallel lines are cut by a transversal:[br][br]1. Are corresponding angles congruent (have the same measure)?[br]2. Are alternate interior angles congruent?[br]3. Are alternate exterior angles congruent?[br]4. Are vertical angles congruent?[br]5. Are same-side interior angles supplementary (sum to 180 degrees)?[br]6. Are same-side exterior angles supplementary?
