Question

which angles are vertical to each other? ∠8 and ∠7 ∠1 and ∠6 ∠6 and ∠8 ∠5 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

• Option 1: ∠8 and ∠7 are adjacent angles, not vertical angles.
• Option 2: ∠1 and ∠6 are not formed by the same two - intersecting lines, so they are not vertical angles.
• Option 3: ∠6 and ∠8 are adjacent angles, not vertical angles.
• Option 4: When two lines intersect, ∠5 and ∠3 are opposite each other. So they are vertical angles.

Answer:

∠5 and ∠3
