In order to use this lesson most effectively, it is suggested that the instructor read all materials given and choose those that best suit the needs of the class. One suggestion use is to have students begin with the definition page. Following each definition, there is a link to an investigation using The Geometer's Sketchpad.
If The Geometer's Sketchpad is not available, you may download a demo copy at
The Geometer's SketchpadAfter that, students can do more exploring using Java applications and Kali. For the Java applications, your browser needs to be Netscape version 3.0 or later. Do not try the Java applications on versions before 3.0. Kali can be downloaded from The Geometry Center A Web guide to using Kali on a Macintosh is also available. If your browser supports JavaScript, answers to the questions on the Kali Web pages can be checked interactively.
Paper and pencil exercises are also available to reinforce concepts explored in the computer activities. Feel free to print any of them and duplicate them for classroom use.
