Alternate angles on the transversal line are equal
If a transversal intersects a pair of lines and the alternate angles are congruent, the lines are parallel.
Alternate Exterior Angles are created where a transversal crosses two (usually parallel) lines. Each pair of these angles are outside the parallel lines, and on opposite sides of the transversal.
