Theory:

The angle bisector is formed when a line or line segment divides an angle into two equal parts.

Follow the below steps, construct the bisector of the \(∠A\) with the measure \(60°\).
 
Step 1: Draw the given angle \(∠A\) with the measure \(60°\) using the protractor.

Step 2: Taking \(A\) as centre and convenient radius, draw an arc to cut the two lines such that the arc meets the lines at \(B\) and \(C\).

Step 3: With the same radius and \(B\) as centre, draw an arc, and with \(C\) as centre and with the same radius, cut the already drawn arc.

Step \(4\): Join \(A\) and the point of intersection of the arcs to form the angle bisector.
