Quadrilateral Tesselation

See the Framework for teaching mathematics: Years 7, 8 and 9, supplement of examples, pages 187 to 189, 203 and 215.

You can manipulate the above quadrilateral tessellation yourself. Either download the file 'QuadTess.fig' and open it with the program 'Cabri Geometry II Plus' or the file QuadTess.gsp and open it with the program The Geometer's Sketchpad

If you do not have either program, you can download free trials at the links above.

Cabri Geometry II files are text files. If, when you click on the Cabri file links, your browser window fills with text, either save it as a text file with the .fig extension, or alternatively right-click to download the file, choosing to "save as" to your PC.
