In a pair of alternate exterior angles, if one angle measures 120 degrees, what is the measure of the other angle? (2021)
Step 1: Understand what alternate exterior angles are. They are pairs of angles that are on opposite sides of a transversal and outside the two parallel lines.
Step 2: Remember that when two parallel lines are cut by a transversal, alternate exterior angles are equal.
Step 3: Identify the measure of one angle in the pair. In this case, one angle measures 120 degrees.
Step 4: Since alternate exterior angles are equal, the measure of the other angle is also 120 degrees.
