Quadrilaterals
(already made -- ready to use file)

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

Investigate the parallelogram, rectangle, square, rhombus, and isosceles trapezoid with this menu driven exploration.
The pages with all options "in view" are shown below.

This program was designed to be shown on a 800 x 600 computer screen.
This is one file with 6 pages.

Each of the 5 quadrilateral pages allows for the dragging of the vertices of the quadrilateral
and the viewing (or hiding) of:

  • Measurements of Sides

  • Measurements of Angles

  • Measurements of Diagonals

  • Measurements Related to Diagonal Intersection

  • Measurements of Angles Formed Where Diagonals Intersect

 

These .gsp and .pdf files are to be used only by individual teachers in their own classrooms.

If you do not have access to GSP software, you can access similar parallelogram, rectangle, rhombus, and isosceles trapezoid explorations 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.
