Mathematics 9: Focus on Understanding

Diagrams for use in Chapter 9: Geometry II

The diagrams provided here have been created to act as companions to the various activities given in the Mathematics 9 textbook. They have been made from the information given in various explorations and questions for Chapter 6. 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.

Please Note:
Files for Units 9.2 and 9.3 are currently provided in two formats also. They are provided as .jpg images, suitable for printing.
Google Sketchup was used to create these 3D shapes, and files ending in .skp cannot be opened without that software installed. This is free software - click here to go to the download site. You will need to consult with your Board Technology Coordinator about having this software installed on computers in your school.
