Question

which angle is vertical to ∠3? ∠6 ∠2 ∠5 ∠1

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent.

Step2: Identify vertical angle to ∠3

In the given figure, when two lines intersect at the point where angles are formed, ∠3 and ∠2 are opposite each other. So, ∠2 is the vertical angle to ∠3.

Answer:

∠2
