Geometer's Sketchpad and GeoGebra Prepared Sketches and Scripts
The real danger is not that computers will begin to think like men, but that men will begin to think like computers.
Sydney J. Harris, Return to Mathematical Circles (1988)

Geometers Sketchpad 4.5.exe, Icon8FC70113.exe, GSPVietnamese.exe, GSP312N.exe or GSP 4.07GR.exe are the common file names to indicate this program's installer. The following versions: 5.0, 4.0 and 3.0 are the most frequently downloaded ones by the program users.

This page contains Geometer's Sketchpad 4.0 and GeoGebra programs and scripts created by Timothy Peil for use in the corresponding chapters. Other Sketchpad 4.0 programs and scripts created by others are listed at the bottom of this page.

The left-hand figure illustrates the location of the custom tools for the Poincare Half-plane in the prepared Geometer's Sketchpad sketch. To open the context menu press and hold the pointer on the Custom Tool icon, which is the arrow followed by the three vertical dots. And then select the desired tool. The custom tools work the same as the standard tools.
The right-hand figure illustrates the location of the custom tools for the Poincare Half-plane in the prepared GeoGebra sketch. To open the context menu click on the custom tool icon, in this case, the icon says Poincare Half-Plane.

At any time during his show, the performer displays an artist’s sketch pad and draws an outline of a face. Unexpectedly, the drawing somehow becomes animated with moving eyes and mouth! This 50 sheet sketchpad is the refill for Ultimate Sketch Pad 4.0. So before I started using fire alpaca I used a website called sketch pad and sketch pad 4.0,going ba. The Geometer's Sketchpad Version 4 was first released in December 2001, and has been replaced by Version 5, described above. The last minor update to version 4 was 4.07, and version 4 users are encouraged to use that version until they can upgrade to version 5.
