Do any of you guys know the definition of the converse of alternate exterior angles postulate?
If two lines in a plane are cut by a transversal so that a pair of alternate exterior angles is congruent, then the two lines are parallel.
In the image, if you know/prove ∠1 ≅ ∠8 OR ∠2 ≅ ∠7, then lines a and m are parallel.
