Steve's Math 334 Hyperbolic Tools Page - Spring 2012
To my students: Below are files containing tools for
Geometer's Sketchpad constructions in the different models of hyperbolic
geometry.
To all others: If you have reached this page with the intent of
downloading a full package of Geometer's Sketchpad tools for hyperbolic
constructions, those tools have been temporarily removed while I teach a
geometry course this spring. Those files will be accessible once again
this summer. If you need to access these files before then, please contact
me at
szydliks@uwosh.edu.
I apologize for any inconvenience.
Students, you can import the tools into your appropriate hyperbolic universe
as follows:
* Note: These are instructions for downloading on the Macs -
Using a PC will likely be slightly different.
- Click on the appropriate "zip" file (e.g. "kdtools.zip" for the
Klein model tools). The Mac should then automatically save the file to
the Desktop as a Sketchpad file (e.g. "kdtools.gsp").
- Open the appropriate file of tools (e.g. "kdtools.gsp")
- Open your hyperbolic universe (e.g. "Klein.gsp")
- You want to copy tools into your Klein universe, so make sure that you are
working in "Klein.gsp". Click (and hold) the "Script
Tool" button in Sketchpad. This is the button on the bottom
left
of the Sketchpad desktop. Select "Tool Options...," then
"Copy Tool."
- Select "kdtools", then one-by-one import all of the tools from "kdtools" into "klein.gsp."
If you were successful in your Klein line and Klein segment constructions
during our last activity,
there's no need to import those tools into your world.
- Save your "Klein.gsp" file which now contains all of these new
construction tools. Note that to use these tools effectively,
you must have the center of your Klein disk labeled "K-Disk
Center" and the radius point labeled "K-Disk Radius".
- Repeat the steps above in an analogous way to download the tools for the Poincaré
half-plane. Use the tool file titled "phtools.zip" below,
and copy the given tools into your "Poinhalf.gsp" file. If
you were successful in creating the half-plane line and segment tools in our
last activity, then there's no need to import these tools into your
world. Save your file.
*Very Important Note: To use the half-plane tools,
you need to label the horizontal line that defines your half-plane
universe. It needs to be called "x-axis". Make this
change in your half-plane universe before you save and close it.
- Repeat the steps above in an analogous way to download the tools for the Poincaré
disk. Use the tool file titled "pdtools.zip" below, and copy
the given tools into your "Poindisk.gsp" file. If you were
successful in creating the Poincaré line and segment tools in our
last activity, then there's no need to import these tools into your
world. Save your file.
If you have any questions or find any errors on this page or in
my tools, please notify me at

Thanks!
