Question

which angles are vertical to each other? select all that apply. ∠4 and ∠2 ∠1 and ∠3 ∠4 and ∠5 ∠4 and ∠1

Explanation:

Step1: Recall vertical - angle definition

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

Step2: Identify vertical - angle pairs

In the given figure, when two lines intersect, ∠1 and ∠3 are non - adjacent and opposite each other, so they are vertical angles. Also, ∠2 and ∠4 are non - adjacent and opposite each other, so they are vertical angles.

Answer:

∠1 and ∠3, ∠2 and ∠4
