<p>Constructible - A package for computing and visualizing constructible numbers.</p>

<h1><a class='u' href='#___top' title='click to go to top of document'
name="DESCRIPTION"
>DESCRIPTION</a></h1>

<p>This module provides the basic tools to build geometric constructions with ruler and compass.
This is how constructible numbers arise,
these are numbers which can be constructed by initially taking 2 points and using only ruler and compass to build additional points,
and those additional points must only be at intersections of either lines or circles drawn by means of ruler and compass.</p>

<p>This module also provides an interface to Maxima(which is a full-featured CAS).
Here are some examples:</p>
