GeoGebra works with three types of item types:
You can see A, B and C in the right figure:
- Frit punkt (dark blue, punkt A) – Disse punkter kan flyttes helt frit.
- Afhængigt punkt (light blue, point B) – Disse punkter kan flyttes, but “stuck” on something and can not be moved freely around.
- Låst punkt (dark gray, point C) – Disse punkter kan ikke flyttes og sidder fast på noget, can be, for example coordinates.

bruges, When you need to find the intersection between eg two graphs, lines or the like.
