Question

Which of the following is the pair of adjacent angle in the polygon given below?

• A. $\angle FAB$ and $\angle ABC$
• B. $\angle BCD$ and $\angle ABC$
• C. $\angle FED$ and $\angle ABC$
• D. $\angle FAB$ and $\angle CDE$

Answer 1

Answer: (A), (B)

$\angle BCD$ and $\angle ABC$

Adjacent angles are those angles which share the common side.

Here, $\angle FAB$ and $\angle ABC$ are adjacent angles as sharing $AB$ as common side.


And, $\angle BCD$ and $\angle ABC$ are also adjacent angles as sharing $BC$ as common side.
So, option $\left(a\right)$ and $\left(b\right)$ correct.
