Question

In the given figure, the adjacent angle to $\angle POQ$ is ______ .

• A. $\angle POR$
• B. $\angle ROQ$
• C. $\angle POR$ and $\angle QOR$
• D. None of the above

Answer 1

The correct option is B

$\angle ROQ$

Two angles are adjacent if they have



(i) a common vertex

(ii) a common arm and

(iii) the non common arms are an either side of the common arm.

In the given figure 'O' is the common vertex.

If we observe both the figures, only fig. (b) satisfies the (iii) condition that

the non common arms are on either side of the common arm.

So $\angle ROQ$ is adjacent to $\angle POQ$
