Question

which angles are supplementary to ∠afb? select all that apply.

Explanation:

Step1: Recall supplementary - angle definition

Two angles are supplementary if their sum is 180 degrees.

Step2: Analyze linear - pair angles

Angles that form a linear pair are supplementary. ∠AFB and ∠EFA form a linear pair since they are adjacent and their non - common sides are opposite rays. Also, ∠AFB and ∠CFE are vertical angles to angles that form linear pairs. Since vertical angles are equal and angles in a linear pair are supplementary, ∠AFB is supplementary to ∠CFE. And ∠AFB and ∠DFE are also related in such a way that they are supplementary.

Answer:

∠DFE, ∠EFA, ∠CFE
