Question

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

Explanation:

Step1: Define corresponding angles

Corresponding angles are in the same relative position. $\angle1$ and $\angle5$ are corresponding angles as they are both above the parallel - lines $a$ and $b$ and to the left of the transversal $n$.

Step2: Define alternate interior angles

Alternate interior angles are between the parallel lines and on opposite sides of the transversal. $\angle3$ and $\angle5$ are alternate interior angles.

Step3: Define alternate exterior angles

Alternate exterior angles are outside the parallel lines and on opposite sides of the transversal. $\angle2$ and $\angle8$ are alternate exterior angles.

Answer:

(a) $\angle1$ and $\angle5$
(b) $\angle3$ and $\angle5$
(c) $\angle2$ and $\angle8$
