Inclusive definition of trapezoids
As far as modern post-secondary educators are concerned, parallelograms are trapezoids. Since many educators have forwarded solid practical reasons for the inclusive definition, and it is preferred by experts, and the exclusive definition has no such backing, I would like to alter this article to reflect the inclusive definition. I would be happy to field questions or facilitate discussion as I have been researching this point recently, and I have the resources and citations handy.

Also, I didn't intend to imply that I would be completely eradicating the old definition. Because the exclusive definition is so widespread, I would leave explanation about it and its relationship to the inclusive definition. Rschwieb (discuss • contribs) 17:44, 27 November 2012 (UTC)
