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

Looking at the figure, ∠1 and ∠3 are vertical angles (opposite each other when two lines intersect).

Step3: Identify vertical angles for ∠2

∠2 and ∠4 are vertical angles (opposite each other when two lines intersect).

Answer:

For ∠1 and?, the answer is ∠3; for ∠2 and?, the answer is ∠4. So the pairs are ∠1 and ∠3, ∠2 and ∠4.
