Transformations
(already made -- ready to use file)

(Materials for use with Geometer's Sketchpad 4.0 or higher -- not GSP 3.0)

Investigate reflections, translations, dilations, glide reflections, rotations of 90, 180, 270, rotations of any degree, and composition of reflections with this menu driven exploration.  The pages with all options "in view" are shown below.

  This program was designed to be shown on a 1024 x 768 computer screen.
(This is one file containing 8 different pages.)

Each of the 7 transformation pages allows for the dragging of the vertices of the figures
and the viewing (or hiding) of various options.  Several pages also have animations.

The coordinates of the figures have been set to integer values for easy examination of relationships between coordinates.  Do NOT "save" changes when done and these original settings will remain for the next class or viewing.

This package is great for classroom demonstration as items are large enough to be seen in a classroom setting.  If used in conjunction with the accompanying worksheets, the package is ideal for student exploration.

This package is designed for the Algebra2 level student, but could be used for a more basic introduction to transformations as well.

These .gsp and .pdf files are to be used only by individual teachers in their own classrooms.
Please refer to Terms of Use.

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.  "Animate" is activated when clicked and will terminate when clicked a second time.
  • 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.
