What special property distinguishes rectangles from non-rectangular parallelograms?

What are the two special properties of rhombuses that distinguish them from other parallelograms?

Directions: Using Definition to Construct Rectangle and Verifying Special Property

1. Use the DEFINITION of rectangle to construct a rectangle on the GeoGebra applet below. 2. Use GeoGebra to verify the special property.

Create a Rectangle and Verify Special Property

Briefly explain how you verified the special property of rectangles.

Directions: Using Definition to Construct Rhombuses and Verifying Special Properties

1. Use the DEFINITION of rhombus to construct a NON-RECTANGULAR rhombus on the GeoGebra applet below. ( Try this yourself, but if you need help see the video below.) 2. Use GeoGebra to verify the two special properties of rhombuses. 3. Be prepared to show and explain how you verified the two special properties.
