In the figure with $PQ = x$ cm and $OR \perp PQ$ , $\angle QOS$ equals—

a $\angle POS$
b $\angle POQ$
c $\frac{1}{2}\angle POQ$
d $90^{\circ}$

ব্যাখ্যা

Since $OR \perp PQ$ from the centre, $R$ is the midpoint of chord $PQ$ , so $OS$ (along $OR$ ) bisects the central angle $\angle POQ$ . Therefore $\angle QOS = \frac{1}{2}\angle POQ$ .
