drgeo - a GTK+ interactive geometry program
Dr. Geo is the OFSET’s interactive geometry program.
It is a sort of vector drawing software but with mathematical
constraints - we also call this interactive geometry.
It allows one to create geometric figure plus the interactive
manipulation of such figure in respect with their geometric
constraints. It is useable in teaching situation with students from
primary or secondary level.
