Question

angle 4 and angle 8 * alternate interior alternate exterior

Explanation:

Step1: Recall angle - pair relationships

When two parallel lines are cut by a transversal, different angle - pair relationships exist. Alternate interior angles are between the two parallel lines and on opposite sides of the transversal. Alternate exterior angles are outside the two parallel lines and on opposite sides of the transversal.

Step2: Identify the position of ∠4 and ∠8

∠4 and ∠8 are outside the two parallel lines and on opposite sides of the transversal.

Answer:

alternate exterior
