Dr. Geo, a software to design & manipulate interactive geometric sketches. It helps kids to explore geometry. Distributed with its source code it is modify-me-ready.
C.a.R. (Compass and Ruler) is an interactive geometry program for simulating compass-and-ruler constructions on a computer. It supports many advanced features including: macros, construction animations, drag-and-drop construction, arithmetic computations, numerical solutions...
Dynamic geometry software based on René Grothmann's Compass and Ruler (CaR) software from 1989.
