===Converse Corresponding Angles Postulate - If two lines are cut by a transversal so that corresponding angles are congruent then the lines are parallel===

The Corresponding angles converse postulate helps prove that two lines are parallel. When corresponding angles are congruent, that proves that the two lines are parallel. -Vinokur

in this example, since angles 1 and 3 are corresponding angles and are congruent, lines M and N are parallel -Vinokur Question 1: Is line l parallel to line m?- Michael Manhart



Question 2: Solve for X and are they congruent? - Josh Berkowitz

Answer Key : 1. No because the corresponding angle are not congruent 2. X=5 and yes they are congruent
