Question

which angles are congruent to ∠7 select all the correct answers a ∠5 b ∠8 c ∠7 d ∠9 e ∠10 f ∠12

Explanation:

Step1: Recall angle - congruence rules

Vertical angles are congruent and corresponding angles are congruent when lines are parallel.

Step2: Identify vertical and corresponding angles to ∠7

∠7 and ∠5 are vertical angles, so ∠7≅∠5. Also, if the lines are parallel, ∠7 and ∠11 are corresponding angles, so ∠7≅∠11. But among the given options, only ∠5 is present.

Answer:

A. ∠5
