The steps are as follows:
1. Put the compass at one point on the vertex of the angle and draw an arc that intersects both sides of the angle.
2. Now, draw an arc from each of these points of intersection, in such a way that the arcs intersect in the interior of the angle. Keep the compass open in the same amount throughout this step.
3. Now, draw a ray/line from the vertex of the angle to the intersection point of the two arcs drawn during step 2.
How many arcs would you make? We will draw 3 arcs.
