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.

  1. 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").
  2. Open the appropriate file of tools (e.g. "kdtools.gsp")
  3. Open your hyperbolic universe (e.g. "Klein.gsp")
  4. 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."
  5. 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.
  6. 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".
  7. 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.

  8. 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.
File Name Description
kdtools.zip Klein disk tools
phtools.zip Poincaré half-plane tools
pdtools.zip Poincaré disk tools
