1. an interactive geometry program for KDE With this program you can do geometry on a computer just like you would on a blackboard in a classroom. However, the computer allows you to go beyond that, since KGeo is designed to do interactive geometry. For example, the program allows you to move and change geometrical drawings, so that you can see all the changes. Imagine a triangle that can be altered into any shape you want, just by moving its corners around. At the same time you can see that the angles change, but that they always add up to 180 degrees. KGeo was formerly called KEuklid. From Debian 3.0r0 APT
