Question

give a pair of corresponding angles, a pair of alternate exterior angles, and a pair of alternate interior angles.

Explanation:

Step1: Recall corresponding - angles definition

Corresponding angles are in the same relative position. For example, $\angle1$ and $\angle3$ are corresponding angles.

Step2: Recall alternate - exterior angles definition

Alternate exterior angles are outside the two parallel lines and on opposite sides of the transversal. $\angle1$ and $\angle8$ are alternate exterior angles.

Step3: Recall alternate - interior angles definition

Alternate interior angles are between the two parallel lines and on opposite sides of the transversal. $\angle2$ and $\angle7$ are alternate interior angles.

Answer:

(a) $\angle1$ and $\angle3$
(b) $\angle1$ and $\angle8$
(c) $\angle2$ and $\angle7$
