Kig

Kig is an interactive mathematics software for learning and teaching geometry. It allows to explore mathematical figures and concepts using the computer and also can serve as a drawing tool for mathematical figures. Constructions can be made with points, vectors, lines, and polygons and all elements can be modified directly by using the mouse. Kig helps teachers and students to make conjectures and to understand how to prove geometric theorems.

Additional information

Since Kig can import and use third-party macros as built-in objects, it can have new objects, being more and more powerful.

You can extend Kig with macros written in Python. Please look at the Kig Python Scripting API Documentation.

You can also download and import these macros:

cirkel: A circle BTP constructed using the circle BCP
ConicByLocus: A conic constructed as a locus
ConicCenter: The center of a conic
LineConicMainAxis: The main axis of a conic
LineConicSecondAxis: The secondary axis of a conic
Translatie: Mirror a point using the translation
Baricenter - Circumcenter - Gauss Segment - Incenter - Inscribed circle - Ortocenter:
- Baricenter of a triangle, given the vertices
- Circumcenter of a triangle, given the vertices
- Gauss Segment of a triangle, given the vertices
- Incenter of a triangle, given the vertices
- Inscribed circle on a triangle, given the vertices
- Ortocenter of a triangle, given the vertices
star5 - star5b: Two different ways to construct a star
TropicalLine1pt - TropicalLine2pt - TropicalLineLineIntersection - TropicalConic:
- A tropical line constructed using its centre point
- The stable tropical line passing through two points
- The stable intersection of two tropical lines, to select a tropical line, select its centre point
- Stable Conic Passing through 5 points
These macros require a Kig version with the Python script.
