Write-Up #5. The write-up for this assignment is to create a file
on your home page with links to various GSP script tools
you have produced. I anticipate that some of the following list
will be included, but that you will also add items to the list
as the quarter progresses. The write-up will be a library
of GSP files with script tools..
The creation of a personal library of GSP script tools for doing
constructions you might use several times is an efficient way
to organize and store your work. As we have observed students
working on problems in our classes, we have been surprised by
the number of times we have seen someone repeat a complete construction.
Using a script tool, for example, to construct the circumcircle
4 times makes more sense than repeating the construction 4 times
from scratch on the same figure.
Making a script tool. The simplest way to make a script in GSP 4.02 is to complete a desired construction, select all (either from the menu or by drawing a box around it), and then going to make the script tool using the script tool control in the toolbox. You may want to annotate the comment section to a) help identify "given" objects for the script tool and b) to indicate whose script tool it is. To save a script tool so it is always available on YOUR computer, it must be saved to the TOOL FOLDER in the folder containing the Sketchpad application. To make it available in your web document, your save the file to your html document folder and make a link to it as a GSP helper application.
Here is a list of script tools we think would
be worth saving and using in your work with GSP. We are sure you
will add to the list as you develop more experience with this
application.
1. Centroid
2. Orthocenter
3. Circumcenter
4. Circumcircle
5. Incenter

16. Isosceles triangle, given base and altitude
17. Triangle Centers (H, G, C, and I)
18. Triangle Centers with Euler Line
19. Locus of vertex of a fixed angle that subtends a fixed segment.
20. Divide a segment AB into two parts that form a golden ratio.
21. Pentagon, given a radius.
