Question

which angle number represents the linear pair of ∠krl?

Explanation:

Step1: Recall linear - pair definition

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

Step2: Identify adjacent angle to ∠KRL

∠KRL and ∠LRJ are adjacent angles and their non - common sides (ray RK and ray RJ) are opposite rays. In the given figure, ∠KRL is labeled as angle 1 and ∠LRJ is labeled as angle 3.

Answer:
