Question

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

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are non - adjacent angles opposite each other.

Step2: Identify pairs in the figure

In the given figure where two lines intersect, ∠1 is opposite ∠3 and ∠2 is opposite ∠4. So, the pairs of vertical angles are ∠1 and ∠3, ∠2 and ∠4.

Answer:

• ∠1 and ∠3
• ∠2 and ∠4
