What is the first step in the construction of an angle bisector using only a compass and straightedge?

First step is to set the compass to a convenient width and draw an arc from the vertex of the original angle.

Step-by-step explanation:

To Draw the Angle Bisector of a given angle

First Step:

Construct any two rays or two segments with the help of straight edge , intersecting at a point or have same starting  point.

Or

if an Angle is given, the first step will be :

Put the Pointed end of compass at that point where the two rays intersect,and mark Semicircular arc cutting  both the rays.
