Question

Which two angles are supplementary?

• A. $\angle COF$ and $\angle AOC$
• B. $\angle COF$ and $\angle COE$
• C. $\angle COF$ and $\angle EOD$
• D. $\angle COF$ and $\angle AOE$

Answer 1

Answer: (B)

$\angle COF$ and $\angle COE$ are supplementary because they formed on the line $EOF$

$\Rightarrow \angle COF+\angle COE={180}^{\circ }$

So option $B$ is correct.
