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: 1. Are corresponding angles congruent (have the same measure)? 2. Are alternate interior angles congruent? 3. Are alternate exterior angles congruent? 4. Are vertical angles congruent? 5. Are same-side interior angles supplementary (sum to 180 degrees)? 6. Are same-side exterior angles supplementary?
