Question

which angle number represents the linear pair of ∠krl?

Explanation:

Step1: Recall linear - pair definition

Two angles are a linear pair if they are adjacent and their non - common sides form a straight line.

Step2: Identify linear pair of ∠KRL

∠KRL and ∠LRJ are adjacent and their non - common sides RL and RJ form a straight line. In the given angle - numbering, ∠KRL is angle 1 and its linear pair is angle 3.
