GeoGebraChat is coming! Started by Audrey McLaren, @a_mcsquared, our first time will be on Twitter at #ggbchat, Wed, June 4th, at 8 pm ET (US).
Jim Doherty, @mrdardy, got us started this morning with a good question: Ideas for a smart #geogebra activity to show that parallel pop sides in a quad forces equal length?
Here's his sweet result.

I missed a lot of the discussion, but had to make one when I came back.
