Step 1 step 2 step 3 step 4 p m q m q a b c m q a b d c p m q a b d c draw a … Same-side exterior angles: Angles 1 and 7 (and 2 and 8) are called same-side exterior angles — they’re on the same side of the transversal, and they’re outside the parallel lines. Given: Prove: Prove: 3. Problems include the completion proofs and finding the values of missing angles to make a pair of lines parallel. Prove the Transitivity of Parallels Theorem: If 2 lines are parallel to the same line, then those lines are parallel to each other. If 2 lines are cut by a transversal so that alternate interior angles are congruent then the lines are parallel. Parallel lines proofs worksheet answers.
