Welcome to The 3rd Dimension - The Changing Shape Of Geometry

Part of The Mathematical Association, this site serves as an introduction to Interactive computer based geometry using the Cabri 3d software application.

We will start with the very basics of using the software and expand upon this month by month, hopefully creating a valuable, ever growing archive of geometry tutorials, tips and projects.

The 3rd Dimension will be updated on a 'monthly issue' basis, the first being:
Issue 01: Exploring 3D space with a computer – an Introduction


New issues will be listed on the left hand menu as they become available.

Please take a minute to read the About Cabri 3D and Getting Started pages of the site before diving into the tutorials.
