C-08-Q110mediumsingle_mcq

In Theorem 22, the central angle $\angle AOB$ on diameter $AB$ equals—

aone right angle
btwo right angles (a straight angle)
chalf a right angle
dfour right angles

ব্যাখ্যা

Because $AB$ is a diameter, $A$ , $O$ , $B$ are collinear and $\angle AOB$ is a straight angle. A straight angle measures $180^\circ$ , which equals two right angles.
