Question

Which angle is the adjacent angle to two angles?

• A. $\angle a$
• B. $\angle b$
• C. $\angle c$
• D. There is no such angles.

Answer 1

The correct option is B $\angle b$

$\angle b$ shares common ray with $\angle a$ as well as $\angle c,$ shown here by the dashed line.

Hence, $\angle b$ is the adjacent angle to both $\angle a$ and $\angle c.$
