Question

which angles are vertical to each other? ∠8 and ∠3 ∠6 and ∠2 ∠1 and ∠3 ∠7 and ∠3

Explanation:

Step1: Recall vertical - angle definition

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

Step2: Analyze each option

• For ∠8 and ∠3: They are not formed by the same two - intersecting lines, so they are not vertical angles.
• For ∠6 and ∠2: They are not vertical angles as they are not opposite each other at the intersection of two lines.
• For ∠1 and ∠3: They are vertical angles because they are opposite each other when two lines intersect.
• For ∠7 and ∠3: They are not vertical angles as they are not opposite each other at the intersection of two lines.

Answer:

∠1 and ∠3
