Name a pair of alternate interior angles in the picture below.

Two parallel, vertical lines are cut by a diagonal transversal. Angle A is to the right of the parallel line on the right and above the transversal, angle B is to the right of the parallel line on the right and below the transversal, angle C is to the left of the parallel line on the right and above the transversal, angle D is to the left of the parallel line on the right and below the transversal, angle E is to the right of the parallel line on the left and above the transversal, angle F is to the right of the parallel line on the left and below the transversal, angle G is to the left of the parallel line on the left and above the transversal, and angle H is to the left of the parallel line on the left and below the transversal.

Alternate interior angles are angles that are on opposite sides of the transversal and on the inside of the two lines.

In the given picture, a pair of alternate interior angles is angle C on the left of the parallel line on the right and angle F on the right of the parallel line on the left.
