Question
In figure, $a = b = c$, name the angle which is congruent to $\angle\text{AOC}$
✓
Answer
We have, $\angle\text{AOB}=\angle\text{BOC}=\angle\text{COD}$
$\therefore\angle\text{AOB}=\angle\text{COD}$
Also, $\angle\text{AOB}+\angle\text{BOC}=\angle\text{BOC}+\angle\text{COD}$
$\angle\text{AOC}=\angle\text{BOD}$
Hence, $\angle\text{BOD}$ is congruent to $\angle\text{AOC}.$
