Proof Key Concepts Theorem 3 7 Converse of the Alternate Exterior Angles Theorem If two lines and a transversal form alternate exterior angles that are congruent then the two lines are parallel If amp 1 gt amp 2 then a 6b Theorem 3 8 Converse of the Same Side Exterior Angles Theorem If two lines and a transversal form same side exterior angles
Alternate Exterior Angles Theorem If two parallel lines are cut by a transversal then the pairs of exterior angles are congruent Alternate Exterior Angles Converse If two lines are cut by a transversal so that alternate exterior angles If parallel lines are cut by a transversal a third line not parallel to the others then they are corresponding angles and they are equal sketch on the left side above We know that angle x is corresponding to angle y and that l m lines are parallel they told us so the measure of angle x must equal the measure of angle y
