Kig is a program for exploring geometric constructions.

It is meant as a better replacement for such free programs as KGeo, KSeg and Dr. Geo and commercial programs like Cabri.

Kig is meant as a useful and powerful utility for high school students and teachers, and as a fun project for me and others. I have learned a lot by working on it, and it's fun to work together with other people on it. I've written much of the Kig code myself, but I've also had a lot of help from other people. Please see the about box for more information.
