[Volker Dirr]

Hallo

nice dynamic interactive geomertic software can be used by math students and teachers.

Free Software is available here:

Who knows other free geometric software?

Addendum:
I forgot 2 other projects.
they are part of the kde education project. so linux users already have them installed or can install them from their kde install cd/dvd.
i am not sure about windows users.

wingeom is for windows only, but it run fine with wine under linux.
it look like you can't do everything by mouse. sometimes i must use my keyboard. i am currently not sure if that is an advantage or a disadvantage to users.

i tried your "Romate", but i got error messages. For example:
"java.security.AccessControlExept ... ava.io.FilePermisson /home/volker/Desktop/romate14/58.zi read"
I downloaded you version and uncompressed/unziped it on the desktop. after that i started the index.html. Hyperlinks work well, just the plugins didn't start. i activated java in the settings of my webbrowser. What have i done incorrect? the test page on you website work well. i can see the halfed angle.
