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 Study More Solved Questions / Examples Observe the following diagram and check is it a linear pair Observe the following diagram and check is it a linear pair ?
