What is linear pair of angles?
Linear Pair
When the two adjacent angles are supplementary, such pairs of angles are known as linear pairs.
In other words, a linear pair is a pair of adjacent angles whose non-common sides are rays pointing in the opposite direction.
In the above figure, ∠AOB and ∠BOC are supplementary angles which means,
- ∠AOB $+$ ∠BOC = 180 degrees
And these two are adjacent angles too because they have a common vertex O and a common side OB.
∠AOB and ∠BOC are supplementary as well as adjacent angles, so they are a linear pair.
