Question

what is the supplement to ∠4? ∠1 ∠5 ∠3 ∠6

Explanation:

Step1: Recall supplement - angle definition

Two angles are supplementary if their sum is 180 degrees. In the context of parallel - lines and a transversal, we look for an angle that forms a linear pair with ∠4.

Step2: Identify the supplementary angle

∠4 and ∠5 form a linear pair. A linear pair of angles is supplementary. So the supplement of ∠4 is ∠5.

Answer:

∠5
