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 at each intersection where a straight - line crosses two others. For example, $\angle1$ and $\angle5$ are corresponding angles.

Step2: Recall alternate exterior angles definition

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

Step3: Recall alternate interior angles definition

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

Answer:

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