## tkz-euclide version 4.25c

This version prepares a next version which will use only Lua for the calculations. For this purpose, I have accentuated the separation between definitions and drawing. Thus it is no longer possible to ask for the drawing of exinscribed circles without first going through their definition.

Pure Euclidean Geometry with tkz-euclide v4: You can use the same macros as in tkz-euclide except that tkz-base is no longer loaded. The unit is the cm, you no longer need to specify. This will be the last version before the introduction of Lua. Some notable changes like the disappearance of defining points using macros that draw objects like : \tkzDrawCircle or \tkzDrawTriangle. \tkzDrawCircle still exists but without being able to use options like "ex" or "in". \tkzDrawTriangle on the other hand does not exist any more, instead you must use \tkzDrawPolygon. In order to use options like "equilateral" or "pythagore" you must first use \tkzDefTriangle.

The general idea is to be able to use "lua" for the definition of the new points, which means to make calculations. Then, once the points are obtained, to use TikZ to make all the drawings.

## Euclidean geometry with tkz-euclide (tex, pdf)

This document brings together some notes about tkz-euclide 4, a tool for creating geometric figures. The two most important Euclidean tools used by early Greeks to construct different geometrical shapes and angles were a compass and a straightedge. My idea is to allow you to follow step by step a construction that would be done by hand (with compass and straightedge) as naturally as possible.

## The Pythagorean theorem

This document shows some proofs of the Pythagorean theorem. All the figures are made with tkz-euclide 4.2c. (tex, pdf)
