# 4 Bisect an Angle

- Set your compass to a radius of reasonable distance inside the angle and swing it from the to create an inside the angle.
- . Draw a line () from the 2 points that cross the lines that make the angle.
- Now, the line (
**chord**). You can use the**vertex**as one point, so you only need**arc**outside the chord. Set your compass to approximately ¾ of the length of the line. - Keeping this distance set on your compass, swing
**arcs**from both ends of the line. - Draw a line through the
**vertex**to the intersection of the arcs.
