Resources using Dynamic Geometry

Dynamic Geometry programs are multi-purpose software tools for the mathematics classroom.

The files provided on this site can quite easily be adapted for each of the following software package.

Geometer's Sketchpad Program

Cabri Geometry Program


RITEMATHS files for school use


Geometer's Sketchpad

If your school does not have GSP and you are interested in evaluating the software then follow this link, 

For many ideas for the use of Geometer's Sketchpad, including JAVA SKETCHPAD, and many prepared files, click 101projectideas

Cabri Geometry

Another truly excellent dynamic geometry product in CABRI geometry. Cabri is also available for graphics calculators (TI92 and Voyage 200).


GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus. It received several international awards including the European and German educational software awards.

A quick search will link you to a range of tutorials and examples.




The resources below use Geometer's Sketchpad, although they can also be written in other packages such as Cabri Geometry. Resources files will be regularly added to this collection.


A file to assist students to see how errors in an angle affect distances calculated.

A file to assist students to see how errors in a distance affect distances calculated.

Land Division (zipped gsp)

This real problem, sent in by a farmer, can use ideas of area, similar figures, geometry, trigonometry and quadratic functions. The dynamic geometry file illustrates the problem and facilitates exploration.

Ladder Overhang (zipped gsp) : A ladder leans against the wall of a house and overhangs the roof. When is the overhang the greatest?
For calculus students.

River Bank Area (quadratic function with a maximisation problem)

Shot on Goal (zipped gsp) : Year 10 trigonometry problem with numerical or visual optimisation.

Surd Delights : Four activities for exploring surds making use of dynamic geometry.
