This examples shows how to divide a line into two equal parts using a compass and ruler.

- Start with a line with two end points.
- Draw an arc outward with a radius equal to the distance between the two points.
- Repeat this process with the other point. Label the two points where the arcs intersect.
Draw a line between the two points and label where the line intersects the original line.

We have finished dividing the line into two equal parts.
