Question

Name a pair of angles that are vertical.

  1. Angles 4 and 5
  2. Angles 7 and 9
  3. Angles 8 and 9
  4. Angles 5 and 7

hintHint:

Vertical angles are formed when two lines meet each other at a point.

The correct answer is: Angles 7 and 9


    Angles 7 and 9 are vertical angles.

    They are always equal to each other. In other words, whenever two lines cross or intersect each other, 4 angles are formed. We can observe that two angles that are opposite to each other are equal and they are called vertical angles.
