Rectangle Action!

[color=#000000]Slide the slider slowly in the applet below. Be sure to repeat this process a few times, making sure to change the locations of the rectangle's [/color][color=#ff00ff]3 pink vertices[/color] [color=#000000]each time before re-sliding the slider. [/color] [br][br][br][b][color=#0000ff]What properties, illustrated here, are [/color][color=#38761d]unique [i]only to rectangles[/i][/color][color=#0000ff] and not to other parallelograms? [br][br]Are there any other (older) theorems illustrated here? If so, describe.[/color][/b]
