This site contains downloadable, interactive computer files to accompany many papers in the book, Geometry Turned On. Some files have been designed with explanations to function as an interactive environment. Others are in the form just as they were used to produce figures for the corresponding paper in the book and so may require the paper for an explanation.

File Info

The downloadable files are either Geometer's Sketchpad files or Cabri Geometry II files.

• All files are available in a "universal" format usable by Macintosh or Windows/DOS versions of the programs. Files names are in DOS format that is usable by either version of the software.
• In addition, for some papers, files are optionally available in a Macintosh-only version submitted by the authors with longer, descriptive names chosen or else usable by earlier versions of the software.

Software Needed

• The Geometer's Sketchpad, version 3.0 or later will open all the Sketchpad files. Some files may be opened by earlier versions. If you do not have a copy of this version of Sketchpad, you can open and manipulate the files by downloading the free Demo Version.
• To open the Cabri files, you need Cabri Geometry II, version 1.1. The files are saved in the Cabri(Text) format that is usable by both Macintosh and DOS versions of the software. If you do not have a copy of this version of Cabri, you can open and manipulate the files by downloading the free Demo Version.

Download Help

Files can be obtained three ways.

Each paper in the book has an individual page which can be reaching from the list of titles on the Table of Contents Page.

Almost all the papers are accompanied by downloadable files. A sampling of these files have individual links on the paper's page. If you click on the link to one of these files, then

• if you have configured your browser so that Sketchpad and Cabri are helper applications, then the file will pop up in a window opened by Sketchpad or Cabri;
• otherwise, the file will be downloaded by your browser.

Download all the files for a particular paper from the web page for that paper, which can be reached from the Table of Contents Page.

• Files in universal format in a Zip archive. These files can be used by either Macintosh or Windows/DOS. To extract the files requires a utility to unzip the archive.
• Files in universal format in a Macintosh self-extracting archive, encoded in Binhex format. These files can be used by either Macintosh or Windows/DOS but must be extracted on a Macintosh with a utility such as Stuffit Expander (included with most Macintosh Web browsers).
• Optional Macintosh version. For some papers, an additional Macintosh version is included, either because the files have longer, explanatory names or else use an earlier version of Cabri.

• Macintosh-only version. When available, this substitutes the Macintosh files with long names for those with shorter, DOS-style names. If Cabri files are available for an earlier version of Cabri, these files are included along with the Cabri(Text) versions.
