Question

which angles are vertical to each other? ∠3 and ∠10 ∠6 and ∠14 ∠9 and ∠13 ∠12 and

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and have equal measures.

Step2: Analyze each option

For ∠3 and ∠10, they are not formed by the intersection of the same two - line pair. For ∠6 and ∠14, they are vertical angles as they are formed by the intersection of two lines and are opposite each other. For ∠9 and ∠13, they are not vertical angles.

Answer:

∠6 and ∠14
