Answer:
∠2 and ∠5
Step-by-step explanation:
Vertical angles are opposite angles formed by two intersecting lines. In this diagram, there are three intersecting lines, so many possible vertical angles. Of the choices given, ∠2 and ∠5 are vertical angles because they are formed by the intersection of the vertical line and the diagonal line. The other options are not possible because they are all pairs of adjacent (side by side) angles and not opposite angles.
