Observe the following diagram and check is it a linear pair ? In the given diagram: ∠ 1 and ∠ 2 are supplementary to each other i.e. ∠ 1 + ∠ 2 = 110 ° + 70 ° = 180 ° But they are not adjacent angles i.e. they don't have a common arm. And to form linear pair supplementary angles should be adjacent; having common arm. Hence, ∠ 1 and ∠ 2 don't form a linear pair.
