Characterization of a Trapezoid (US) / Trapezium (UK)

Was translating Wikipedia page: [url]http://en.wikipedia.org/wiki/Trapezoid[/url] and didn't believe the characterizations. So I constructed the trapezoid (US) / trapezium (UK) and sure enough they were true :) Am going to try and add this interactivity as html5 to the mk wikipedia page so I uploaded it. Update: Haven't been able to figure out/remember how to embed ggb into wikipedia. I know I can embed videos using Image and an ogv file. Anybody know how to embed ggb?
