tkz-euclide — Euclidean Geometry with TikZ

Release 5.11c — 2025/09/17

Description

tkz-euclide is a LaTeX package for drawing two-dimensional Euclidean geometric figures. It uses a Cartesian orthonormal coordinate system (unit = 1 cm) and provides tools to define points and manipulate them. The goal is to reproduce, step by step, constructions as they would be done by hand, in the most natural way possible.

Recent updates:

• lua option: most calculations can now be performed using Lua.
• mini option: when tkz-euclide is used together with tkz-elements, this option lets tkz-euclide focus only on the drawings.

License

This package is released under the LaTeX Project Public License, version 1.3c or later.
