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

Explanation:

Step1: Recall corresponding - angles definition

Corresponding angles are in the same relative position. For example, $\angle1$ and $\angle5$ are corresponding angles.

Step2: Recall alternate - interior angles definition

Alternate - interior angles are between the two parallel lines and on opposite sides of the transversal. $\angle3$ and $\angle6$ are alternate - interior angles.

Step3: Recall alternate - exterior angles definition

Alternate - exterior angles are outside the two parallel lines and on opposite sides of the transversal. $\angle2$ and $\angle7$ are alternate - exterior angles.

Answer:

(a) $\angle1$ and $\angle5$ (b) $\angle3$ and $\angle6$ (c) $\angle2$ and $\angle7$
