Kig is an interactive geometry application developed by KDE. It allows users to construct mathematical figures and investigate how their properties change when points and other objects are moved.
The application is primarily intended for teaching and learning geometry, but it can also be used to prepare accurate mathematical illustrations. Students can explore relationships between objects through experimentation, while teachers can demonstrate geometric principles using constructions that respond immediately to changes.
Kig supports a wide range of geometric objects, including lines, circles, conic sections and more complex curves. Constructions can incorporate transformations, measurements and dependencies, providing a useful environment for investigating mathematical conjectures.
Users can extend the available construction tools through macros and Python scripting. Kig also offers several ways to export diagrams for use in other applications and documents.
This is free and open source software.
Key Features
- Interactive construction of points, vectors, lines, circles, polygons and conic sections.
- Dynamic manipulation of objects while maintaining geometric relationships.
- More than 40 types of mathematical objects and constructions.
- Geometric transformations including reflection, translation, rotation and scaling.
- Construction and exploration of loci.
- Macros for creating reusable geometric objects from existing constructions.
- Python scripting to extend the available mathematical tools.
- Tools for displaying measurements and mathematical expressions.
- Import facilities for several other dynamic geometry formats.
- Export diagrams as SVG, images, XFig and LaTeX documents.
- XML-based format for storing mathematical constructions.
