Define Linear Pair

Right Angle Acute Angle Obtuse Angle Zero Angle Straight Angle
Complementary Angles Supplementary angles Adjacent Angles Vertical / Vertical Opposite Angles Linear Pair

Before you understand What is a Linear Pair.
You must read and know - What are Adjacent Angles ?

Definition: A Linear Pair consists of a pair of supplementary Adjacent Angles i.e. sum of both the angles is equals to 180, thus forming a straight line and one common side.

Observe the following diagram of a Linear Pair



∠ x and ∠ y are two adjacent angles because:

Both are supplementary to each other i.e.

∠ y + ∠ x = 60° + 120° = 180°

Have one common side "op".

Hence, ∠ x and ∠ y forms a linear pair
