Alain Matthes submitted an update to the
tkz-elements
package.
Version: 4.20c 2025-09-17
License: lppl1.3c
Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
Announcement text:
New triangle methods: thebault/c_c (Thébault’s problem III), mixtilinear_incircle, three_tangent_circles, morley, soddy, napoleon, poncelet_point, orthopole; plus orthopole support for quadrilaterals via helper tkz.orthopole(a,b,c,l). Improvements: circle (common_tangent, orthogonal_through, orthogonal_from, c_cc_p), line (distance), and rewritten triangle methods (symmedian_line, altitude, bisector, bisector_ext, mediator, ex_circle, reflection). Docs: new Best practices subsection, additional examples (Thébault III, Poncelet point for triangle/quadrilateral, orthopole), and assorted fixes. Backward compatible. GitHub introduction Source, roadmap, issues and the full CHANGELOG live on GitHub: https://github.com/al-ma-dev/tkz-elements. Feedback and contributions are welcome (see CONTRIBUTING.md). The PDF manual ships in the repo and on CTAN.

tkz-elements – A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
This package provides a library written in Lua, allowing to make all the necessary calculations to define the objects of a Euclidean geometry figure. You need to compile with LuaLaTeX. The definitions and calculations are only done with Lua.
The main possibility of programmation proposed is oriented “object programming” with object classes like point, line, triangle, circle and now, conic. For the moment, once the calculations are done, it is tkz-euclide or TikZ which allows the drawings.
