Answer
Steps for construction:
$1.$Draw $\angle\text{BAC}=50^\circ$ with the help of protractor.
$2.$With $A$ as the centre and any convenient radius, draw an arc cutting $AB$ and $AC$ at $Q$ and $P,$ respectively.
$3.$With $P$ as the centre and radius more than half of $PQ$, draw an arc.
$4.$With $Q$ as the centre and the same radius as before, draw another arc cutting the previously drawn arc at a point $S.$
$5.$Draw $SA$ and produce it to point $R.$
Then, ray $AR$ bisects $\angle\text{BAC}.$
