Circle exterior angle theorem
WebAlternate Exterior Angles Theorem. If a transversal intersects two parallel lines, then the alternate exterior angles are congruent. Converse also true: If a transversal intersects two lines and the alternate exterior angles are congruent, then the lines are parallel.
