What Are The Properties Of Alternate Exterior Angles? The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate exterior angles are congruent . ∠1≅∠7 and ∠4≅∠6 . What do alternate exterior angles add up to? If the transversal cuts across parallel lines (the usual case)
