Question

in the figure to the right, s||t. use the figure to answer the following exercise.
∠r is congruent to which two of the following angles?
select all that apply

Explanation:

Step1: Recall angle - congruence rules for parallel lines

When two parallel lines are cut by a transversal, corresponding angles are congruent and vertical angles are congruent.

Step2: Identify corresponding and vertical angles to ∠r

∠r and ∠a are corresponding angles (assuming the standard position of angles formed by two parallel lines and a transversal), so ∠r≅∠a. Also, ∠r and ∠e are vertical angles, so ∠r≅∠e.

Answer:

∠a, ∠e
