Mathematics 8: Focus on Understanding
Diagrams for use in Chapter 3: Geometry I
The diagrams provided here have been created to act as companions to the various activities given in the Mathematics 8 textbook. They have been made from the information given in various explorations and questions for Chapter 3. Each diagram was originally created using The Geometer's Sketchpad and then copied into a Microsoft Word document. Files in both formats are listed below.
For your convenience, a .zip file has been created for each format. Downloading and expanding the .zip file will provide you with a folder containing all the documents listed for that format. Click HERE to go down the list to the links for the .zip files. A table of contents with links to the documents (opens in a web browser) is included in the word_files.zip file.
New for January 2009: We have added a new zip file, with all the Geometer's Sketchpad files included. These are the identical files, but translated into French. Click HERE to go to the zip file in French.
