How to Cut a line into N segments

using just a compass and a straightedge

Here we cut a line into 3 segments, but the same approach can be used to cut a line into any number of segments:

Steps:

- Draw a line from the start point, heading somewhat upwards
- Use the compass to divide it into 3 segments
- Use the compass to create a parallel line heading backwards and down from the end point.
- Use the compass to divide it into 3 segments
- Connect the intersection points of the two new lines, and where they cross the original line it will be neatly subdivided.
