If you do not have access
to GSP software, you can access similar polygon files about interior
angles, exterior angles, and regular figures that we have posted at the
Regents Prep Web Site as Internet
active Java Sketchpad files. |
| General (and
simple) Directions: |
|
- Be sure that the students have chosen the arrow in the
upper left hand corner of the screen.
|
 |
- Be sure that the screen is maximized so that the tabs at
the bottom of the screen are visible. (The middle box at
the right is showing a screen in maximized view.)
|
 |
- Read and follow the directions that appear on the page.
"SHOW" means the values will appear when you click on the
button. "HIDE" means the values will disappear when you
click on the button.
|
- To end the exploration, choose FILE - CLOSE. When
the box asking if you wish to "Save Changes" appears, choose
NO. This will keep the file in the same state as
when you started working. None of the students' changes
(or messing) will be saved.
