Question

what is the relationship between ∠1 and ∠2? match each figure with the angle relationship it shows.
① alternate interior angles
② alternate exterior angles

Explanation:

1. For the top figure: ∠1 and ∠2 lie outside the two parallel lines and on opposite sides of the transversal, which fits the definition of alternate exterior angles.
2. For the bottom figure: ∠1 and ∠2 lie inside the two parallel lines and on opposite sides of the transversal, which fits the definition of alternate interior angles.

Answer:

• Top figure ↔ alternate exterior angles
• Bottom figure ↔ alternate interior angles
