Marlene Dwyer, Richard Pfiefer
October 1999, Volume 92, Issue 7, Page 632
This article explores some principles of, and shows several constructions in, hyperbolic geometry using script tools originally created by Mike Alexander and modified by Bill Finzer and Nick Jackiw for The Geometer's Sketchpad (Jackiw 1995). These tools are compatible with The Geometer's Sketchpad 3.0 and 3.05 for both Macintosh and Windows users.
