Question

Write down the pair of adjacent angles shown in the following figure:

Answer 1

Two angles are called adjacent angles, if they have a common vertex and a common arm but no common interior points.

Hence, the following are adjacent angles:

1. ∠AOB, ∠BOC
2. ∠AOB, ∠BOD
3. ∠BOC, ∠COD
4. ∠AOC, ∠COD
