Question

lines a and b are parallel. ∠2 and ∠5 are what kind of angles? answer: ① vertical angles ② adjacent angles ③ corresponding angles ④ alternate interior angles

Explanation:

Step1: Recall definitions

Vertical angles are opposite angles formed by two intersecting lines. Adjacent angles share a common side. Corresponding angles are in the same relative position. Alternate interior angles are between the parallel lines and on opposite sides of the transversal.

Step2: Analyze ∠2 and ∠5

∠2 and ∠5 are between the parallel lines \(a\) and \(b\) and on opposite sides of the transversal.

Answer:

D. Alternate Interior Angles
