Introduction to the Geometer’s Sketchpad

This is the first part of the Geometer’s Sketchpad Essentials Series.  In this post, we will learnabout Geometer’s Sketchpad and its environment before we use the software. Geometer’s Sketchpad (GSP) is a commercial geometry software created my Nicolas Jackiw in the 1980s. It is similar to GeoGebra, but with fewer tools. On the one hand, […]
