Step by Step Solution

  • Lesson Icon

    Step 1

    To find out which pair of angles are vertical angles. We must know that:

    • Vertical angles are formed from two intersecting lines
    • Both angles are non-adjacent
    • Both angles will definitely be congruent (same angle)
  • Lesson Icon

    Step 2

    As for angles I & II, they are not vertical angles. This is because these two angles are adjacent angles.

    Step 3

    Similarly, angles II & III and III & IV are not vertical angles for the same reason as above.

    Step 4

    Only angles I & III are vertical angles as these angles fulfill the properties mentioned in Step 1. Hence, the answer is D.
