``We were missing this???'' by Wkbj79 on 2007-06-04 15:51:12
For those of you who were surprised that an elementary definition of radical was missing from PM, here is an even bigger surprise: Trapezoid was missing!!!

I think I noticed this earlier (back when I suddenly became active again at about June of 2006), but I did not know how to create graphics, it seemed pointless for me to make an entry on trapezoid without graphics, and it slipped my mind to file a request. After a while, the fact that a definition of trapezoid was missing slipped my mind completely.

Anyways, I have tried to list many properties about trapezoids that I know off the top of my head within the entry. I realize that I may have easily left out properties about trapezoids that someone would want in its entry, so I will leave "trapezoid" and its children open for editing for quite some time. On the other hand, I *implore* you not to change my statement about the PM convention. In order for the "trapezoidal rule" to actually use trapezoids, parallelograms (specifically, rectangles) *must* be considered to be trapezoids. Thanks a lot.
