2 Bisect a Line
- Draw a line.
- Set your compass to approximately ¾ of the length of the line. (The important thing is that it is set to more than half. The further away from half way, the more accurate, but the larger the space required becomes.)
- Keeping this distance set on your compass, swing an arc from both ends of the line towards the centre of the line.
- Draw a line, connecting the two intersection points of the arcs.
