kig26.04.3

Build geometric figures from points, vectors, lines, and polygons, then inspect how their relationships change as you manipulate the construction. Kig turns geometry into an interactive drawing environment where a figure is assembled from related objects rather than left as a static illustration. Moving one element with the mouse updates the connected parts, letting you observe the consequences of a change directly.

This hands-on approach supports exploration of mathematical figures and helps learners form conjectures before they tackle formal proofs. Students can investigate geometric relationships, while teachers can lead demonstrations or guided activities in a classroom or other learning setting.

Rather than merely displaying finished diagrams, kig preserves the construction’s interactive behavior, so an adjustment can reveal how the elements depend on one another. That makes it useful for students, teachers, and anyone studying geometry through experimentation instead of only viewing a final result.

KDE develops kig as Education software under an open-source license for Linux systems with snapd, targeting x86_64 (amd64) hardware; the current version is 26.04.3.
