Bennett / Burton / Nelson Cross Sections of a Cube Applet

Go to the Bennett, Burton & Nelson Student Center Page of Interactive Math Applets by clicking here.

Select the Chapter 9 applet--Cross Sections of a Cube. Once you have launched the applet, play around with it a bit to see how it works. Note that the applet is mouse-driven. You click to select points with the mouse arrow and you click in the cube area and move your mouse to rotate your view.

Assignment

Look at all of the items in the drop down menu (also listed below). Your assignment is to:

1. (1 point each) Create the items in the drop down menu and print a picture of each item. Each printed picture must say "You have successfully created a ITEM cross section" where ITEM refers to the list item you are working on. If you have any trouble printing, try a different browser, and, if this does not work, use the Print Screen key (upper right of keyboard on most computers) to capture and then print the image.

2. Answer the following questions
a. (2 points) Which shape was hardest to create and why?
b. (2 points) Are there any listed shapes that are not possible? Explain why in detail.
c. (1 point) Are there any features of the applet that you would like to change? Explain.

HINTS
It is somewhat easier to play around and find some of the various shapes than it is to directly try to find the shape. When you reset the applet you lose your shape, therefore you should use scratch paper and keep track. For example, if you have the applet set on "Scalene Triangle" and you form a Square you won't have the correct message for a square (it will say: The selected points can not form a scalene triangle cross section). However, you will know how to form a square--jot down a note on how to create the square, reset, select the square from the drop down menu and repeat the selected points to successfully create a square.

The shapes you must form are:

  1. Scalene Triangle
  2. Isosceles
  3. Equilateral
  4. Square
  5. Non-square rectangle
  6. Isosceles Trapezoid
  7. (Non-isosceles) Trapezoid
  8. (Non-rectangular) Parallelogram
  9. Non-regular Pentagon
  10. Non-regular Hexagon
The parenthetical words are not listed on the applet but they are assumed by the applet.
