A linear pair can be defined as two adjacent angles that add up to 180° or two angles which when combined together form a line or a straight angle. Three angles can be supplementary, but not necessarily adjacent. For instance, angles in any triangle add up to 180° but they don’t form a linear pair.

Which angle is a linear pair with 1?

A Linear Pair is two adjacent angles whose non-common sides form opposite rays. ∠1 and ∠2 form a linear pair.
