Question

which angle is vertical to ∠3? ∠6 ∠2 ∠1 ∠4

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 the angles are formed, ∠3 and ∠6 are opposite each other. So, ∠3 and ∠6 are vertical angles.

Answer:

∠6
