Some of the tools include a construct function, which allows the user to create objects in relation to selected objects. The Geometer's Sketchpad can measure lengths of segments, measures of angles, area, perimeter, etc. The program allows the determination of the midpoints and midsegments of objects. The program allows the creation of numerous objects which can be measured, and potentially used to solve hard math problems. The program allows "cheat" transformations to create figures impossible to construct under the compass and straightedge rules (such as the regular nonagon). If a figure (such as the pentadecagon) can be constructed with the compass and straightedge method, it can also be constructed in the program. Its accurate drawings of geometric figures make it a useful tool for illustrating mathematical articles for publication. Thus it is a natural tool for making or testing conjectures about geometric figures.
It can manipulate constructed objects "dynamically" by stretching or dragging while maintaining all constraints of the construction so that a seemingly infinite number of cases of a constructed figure can be viewed. It is far more than a construction or transformation tool, however. It also can perform transformations (translations, rotations, reflections, dilations) of geometric figures drawn or constructed on screen. The Geometer's Sketchpad includes the traditional Euclidean tools of classical geometric constructions. Nonetheless, a new (2021) 64-bit version of Mac Sketchpad that is compatible with the new Apple M1 silicon chips is available as part of an ongoing beta test. In June 2019 McGraw-Hill announced they will no longer sell new licenses. There was also a version developed for the TI-89 and TI-92 series of Calculators. It also runs on Linux under Wine with a few bugs.

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 to 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.
