Look at the diagram. which angle is supplementary to ∠doc?

Two angles are supplementary when they add up to 180 degrees.

1. Consider angle ∠COB:

m∠DOC+m∠COB=m∠DOB=180°.

This means that angles ∠DOC and ∠COB are supplementary.

2. Consider angle DOA:

m∠DOC+m∠DOA=m∠COA=180°.

This means that angles ∠DOC and ∠DOA are supplementary.

1. ∠COB; 2.  ∠DOA
