Don't have direct experience with what you want but you may want to
look at Dr.Geo:

http://www.ofset.org/drgeo
"Dr. Geo is a GTK interactive geometry software. It allows one to create
geometric figure plus the interactive manipulation of such figure in
respect with their geometric constraints. It is usable in teaching
situation with students from primary or secondary level."

There's a deb package available at
http://packages.debian.org/unstable/math/drgeo.html

OR

search among categorised tools of a similar nature at
http://richtech.ca/cgi-bin/seul/seulvw.pl?category=Math
or heaps more at
http://packages.debian.org/unstable/math/

Sorry can't give a specific recommendation beyond Dr.Geo.
