Question

which angle is vertical to ∠1? ∠3 ∠4 ∠5 ∠2

Explanation:

Step1: Recall Vertical Angles Definition

Vertical angles are opposite angles formed by two intersecting lines, and they are equal.

Step2: Identify Intersecting Lines for ∠1

Look at the diagram: ∠1 and ∠3 are formed by the intersection of two lines (the lines creating ∠1 and ∠3 cross each other). Check the positions: ∠1 and ∠3 are opposite each other at the intersection point. ∠2, ∠4, ∠5 do not satisfy the vertical angle position relative to ∠1.

Answer:

∠3
