At least one of the applets on this page leads to applets that were written for the Wolfram
Demonstration Project. In order to run them you will need to download
the Wolfram CDF reader [available FREE at

A geometric construction or a series of them may be thought of a
function. Here is an example: Construct the three medians of a triangle.
Reflect the point of concurrence of the medians over each of the sides
of the triangle. These operations define a new triangle. Taken together
these operations are a function from the domain of point triples in the
plane to the range of point triples in the plane. This collection of
applets allows for the exploration of such functions on shapes.Topics include
- medians, altitudes & angles bisectors in triangles
- geometric generalization
- functions on triangles & quadrilaterals
- functions on rectangles, circles, ellipses
- polygons
-
transformations: translation, dilation, rotation, reflection, & combinations thereof
