Question

Choose the correct term and fill in the blanks :

In the figure :

$\angle POR$ and ………… are adjacent angles. ($\angle ROQ$/$\angle SOQ$)

Answer 1

Adjacent angles :

Two angles are said to be adjacent angles, if they have a common vertex, a common arm (or side) and their non-common arms are on either side of the common arm. As :

As shown in the given figure, $\angle 1$ and $\angle 2$ are the adjacent angles.

Now, as per the question :

$\angle POR$ and $\angle ROQ$ have common vertex $O$ and common arm $OR$ between them.

Hence $\angle POR$ and $\angle ROQ$ are adjacent angles.
