Geometric Construction
4 Bisect an Angle
- Set your compass to a radius of reasonable distance inside the angle and swing it from the vertex to create an arc inside the angle.
- . Draw a line (chord) from the 2 points that cross the lines that make the angle.
- Now, bisect 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.
