Answer:
Step-by-step explanation:
From the picture attached,
Lines 'p' and 'q' are the parallel lines and line 't' is a transversal intersecting these lines.
Two pairs of angles (∠2 and ∠7) and (∠4 and ∠5) are the alternate interior angles.
Similarly, two pairs of (∠1 and ∠8) and (∠3 and ∠6) are the alternate exterior angles.
Alternate interior angles are the interior angles between the parallel lines and the transversal line while alternate exterior angles are vertically opposite angles to these interior angles.
