In the figure, x ∥ y and a is a transversal that crosses the parallel lines.
which angle pair forms alternate exterior angles?
∠3 and ∠5
∠2 and ∠6
∠2 and ∠8
∠4 and ∠6

In the figure, x ∥ y and  a is a transversal line that crosses the parallel lines.

∠2 and ∠8 form alternate exterior angles.

Given two parallel lines X and Y and a is transversal

Alternate exterior angles are a pair of angles on the outer side  of each of those two lines but on opposite   sides of the transversal.

When lines are parallel to each other the alternate exterior angles are equal.

∠3 and ∠5 are alternate opposite angles.

∠4 and ∠6  are alternate opposite angles.

∠2 and ∠6 are corresponding angles.

∠2 and ∠8  are alternate exterior angles.
