Dynamic Geometry Explorations

to accompany

A Course in Modern Geometries, 2nd Ed.

The explorations give guided directions for exploring text topics using Geometer's Sketchpad (GS) ( Key Curriculum Press) and Cabri Geometry II (CG) ( Leibniz) or Texas Instruments). Explorations labeled GS or CG give directions specific to the corresponding software, while those labeled DGS can be carried out with either software. Directions can be viewed and printed using Adobe Acrobat Reader. Required files for Geometer's Sketchpad and Cabri Geometry II in Macintosh (MC) and PC versions can be downloaded using Stuffit, WinZip or a similar utility. Links for downloading Adobe Acrobat Reader, WinZip and Stuffit are at the bottom of this page.
