Question

alternate interior
alternate exterior
corresponding
vertical
what type of angles are 1 and 8?

Explanation:

Step1: Recall angle - pair relationships

When two parallel lines are cut by a transversal, different types of angle - pairs are formed. Alternate interior angles are non - adjacent angles between the two parallel lines and on opposite sides of the transversal. Alternate exterior angles are non - adjacent angles outside the two parallel lines and on opposite sides of the transversal. Corresponding angles are in the same relative position with respect to the parallel lines and the transversal. Vertical angles are opposite each other when two lines intersect.

Step2: Analyze the position of ∠1 and ∠8

∠1 is an exterior angle above the top - parallel line and to the right of the transversal. ∠8 is an exterior angle below the bottom - parallel line and to the left of the transversal. They are non - adjacent, outside the two parallel lines, and on opposite sides of the transversal.

Answer:

Alternate Exterior
