As from the previous example, it is ideal that we focus on one surface each time we name a set of three coplanar lines. We want the converse of that, or the same idea the other way around: If a transversal cuts across two lines to form two congruent, corresponding angles, then the two lines are parallel. If they intersect, give the point. Two lines that lie in parallel planes are parallel? Two parallel lines do not intersect each other. Solution: The two lines are parallel as they meet one of the properties of parallel lines "when the alternate interior angles are equal, the lines are parallel".
