Special quadrilaterals, online assignment (I don't have video examples made--they'll be up by the end of the day Friday. Please reload this page if it is after Friday Nov 21 and there still aren't video links).

Open the quadrilaterals sketch in one of these two ways:

Option 1 (this option makes it easy to cut and paste)

• Download and install the free program Geogebra on your computer.
• Download the Geogebra file quadrilaterals.ggb . (If it downloads as a .zip file, you should try changing .zip to .ggb to make the file work). You may also want to download the file quadrilateralsCopies.ggb
• Open quadrilaterals.ggb using Geogebra.
• Video example of doing stuff using Geogebra

Option 2 (with this option, you will need to make screen captures of your examples)

• Open the web sites http://tube.geogebra.org/student/m315177 and http://tube.geogebra.org/student/m315261
• Open your favorite screen capture tool (the Snipping Tool is a free screen capture for Windows that is probably in your Accessories folder; Grab is a free screen capture tool for Mac that is probably in your Utilities folder).
• Video example of doing stuff on the web site part 1, part 2

Fill out this worksheet using your notes from class, the examples on the last page, and examples you make using geogebra. You can print it out and bring it to class, or you can submit it to the D2L dropbox to save paper.
