8. Angle bisector of an angle

 

 

Follow the below steps, construct the bisector of the $∠ABC$ with the measure $60°$.

 

Step 1: Draw the given angle $∠ABC$ with the measure $60°$ using the protractor.

 

 

Step 2: Taking $A$ as centre and convenient radius, draw an arc to cut $AB$ and $AC$. Mark the points of intersection as $E$ on $AB$ and $F$ on $AC$.

 

 

With the same radius and $E$ as centre, draw an arc in the interior of $∠CAB$ and another arc of same measure with centre at $F$ to cut the previous arc.

 

$AG$ is the required bisector of the given angle $∠CAB$.

 

 

Mark the point of intersection as $G$. Draw a ray $AX$ through $G$.
