Question

name the two pairs of vertical angles in the figure. ∠1 and ? ∠2 and ?

Explanation:

Step1: Recall Vertical Angles Definition

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

Step2: Identify Vertical Angles for ∠1

In the figure, ∠1 and ∠3 are opposite each other (formed by intersecting lines), so ∠1's vertical angle is ∠3.

Step3: Identify Vertical Angles for ∠2

∠2 and ∠4 are opposite each other (formed by intersecting lines), so ∠2's vertical angle is ∠4.

Answer:

∠1 and ∠3; ∠2 and ∠4
