package.

Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
Announcement text:

- class development “vector” - added attribute “vec” to the line class - added “at” and “orthogonal” methods to the class “point” - rewriting the function angle\_normalize\_ - modification of the slope attribute for the “line”, now the result is normalized. - the angles of a triangle are also normalized - added function format\_number(number,decimal) sets the number of digits in the decimal part. - added \tkzDN a macro pour formater les nombres dans la partie TikZ \tkzDN[nb_decimal]{number} - added the macro \tkzDrawLuaEllipse draw an ellipse in tikz knowing its center, vertex and covertex. - correction of documentation

The package’s Catalogue entry can be viewed at https://ctan.org/pkg/tkz-elements The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/tkz/tkz-elements/

## 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 ellipse. For the moment, once the calculations are done, it is tkz-euclide or TikZ which allows the drawings.
