- Look at the way the points are defined in the Style Menu.
There are several ways to use the compass tool. First, set up a workspace that looks something like the image:
- Use the Constructions App below to recreate this image by following the instructions.
- Draw circle A through point B.
- Draw segment CD not intersecting the circle centered at A .
- Draw point E not intersecting the circle centered at A or segment CD.
- Make a new segment EF that is the same length as CD.
- Make a circle with the same radius as the circle A centered at E .
