Tools for the Geometer's Sketchpad
by Kyle Schultz
What are tools?
A tool for Geometer's Sketchpad is a
script of steps that produces a specific gemetric construction.
Tools are useful as they can save the time required to construct
complicated figures, allowing the user more time for analysis
of geometric relationships. To use a tool, a specific geometric
figure must be constructed. For example, to operate a tool for
constructing the circumcenter of a triangle, a triangle would
need to be constructed.
How to use tools.
Each table below contains the listed
tools that are available for use by users of this website. To
access the tools in a given table, click the title of that table.
When you click on one of the tool links, a Geometer's Sketchpad
file containing that tool will be made available to open and/or
download. Once you have opened that file, the selected tool will
be available for any sketch with which you are currently working.
Have fun!
