About Kig
Kig is interactive mathematics software from KDE for learning and teaching geometry. You build constructions from points, vectors, lines and polygons, then drag elements with the mouse to see how the figure changes. This helps students form conjectures and understand how geometric theorems are proved. It also works as a drawing tool for mathematical figures.
Kig can import third-party macros as built-in objects and can be extended with Python scripts. It runs on Linux and macOS.
Strengths
- Constructions update live as you drag elements
- Extensible with macros and Python scripting
- Doubles as a tool for drawing mathematical figures
Limitations
- No Windows or mobile version listed
- Narrower in scope than GeoGebra
