The Geometer's Sketchpad includes the traditional Euclidean tools of classical geometric constructions. A new (2021) 64-bit version of Mac Sketchpad that is compatible with the new Apple silicon chips is available as part of an ongoing beta test. It also runs on Linux under Wine with a few bugs.
Present versions run Microsoft Windows and Mac OS 8. Nicholas Jackiw, a student at the time, was the original designer and programmer of the software, and inventor of its trademarked ' Dynamic Geometry' approach he later moved to Key Curriculum Press, KCP Technologies, and McGraw-Hill Education to continue ongoing design and implementation of the software over multiple major releases and hardware platforms. It was created as part of the NSF-funded Visual Geometry Project led by Eugene Klotz and Doris Schattschneider from 1986-1991 at Swarthmore College. The Geometer's Sketchpad is a commercial interactive geometry software program for exploring Euclidean geometry, algebra, calculus, and other areas of mathematics.
