Question

Draw an angle of measure ${147}^o$ using protractor and construct its bisector.

Answer 1

$1$Draw a line $OA$.

$2$using protractor and center $O$ draw an $\angle AOB={147}^{\circ }$

$3$ Now taking $O$ as center and any radius draw an arc that intersects $OA$ and $OB$ at $p$ and $q$.

$4$ Now take $p$ and $q$ as centers and radius more than half of $PQ$, draw arcs

$5$ Both the arcs intersect at $R$

$6$ join $OR$ and produce it.

$7$.$OB$ is the required bisector of $\angle AOB$
