What is the first step when constructing an angle bisector using only a compass and a straightedge?

Solution:

To draw an angle bisector, using only a compass and a straight edge, we first need to place the compass on the vertex of the angle.

Draw an arc across both legs of the angle.

Now, draw a straight line from the vertex to the intersection of the 2 arcs. This is the angle bisector.

Therefore, the first step is to draw arcs through both legs of the angle.

What is the first step when constructing an angle bisector using only a compass and a straightedge?

Summary:

The first step when constructing an angle bisector using only a compass and a straightedge is to draw arcs through both legs of the angle, centered at the vertex of the angle.
