of opposite parallel sides?

Basically - is a square a trapezoid? What's the most commonly accepted definition of trapezoid?

Yeah, thanks fluff. There are people on this forum with far more credibility and advanced knowledge of the maths than the 4,390,000 often conflicting results of a Google search. Go troll somewhere else.

a trapezoid is a bone in the wrist at the base of the metacarpal of the index finger. I'll never understand why fluffs won't pull their fingers out of their butts and flip through a dictionary. why would you come here looking for a commonly accepted definition? you're welcome fluff.

plus, a square is not a trapezoid because it has more than one pair of parallel sides.

My understanding is that there isn't consensus on the issue.

that's the definition of humanity. Mathematics Dictionary 5th edition does differ from Merriam-Webster's though, apparently a square can be a trapezoid, it just depends on which idiot is looking at it.

awww, you mad bro?

and yeah looks like the results you've got from this thread are lightyears above and beyond what you'd find just by googling it

Dibs - a square is a trapezoid if the definition of a trapezoid is any quadrilateral with at least one pair of parallel sides. If, however, the definition is that a trapezoid is a quadrilateral with ONLY one pair of parallel sides, then a square isn't a trapezoid because it has two. There are two conflicting theories. Just as the two conflicting theories of whether or not .9 repeating = 1. However, one theory must be more widely accepted than the other and there are people on here (I'm waiting for you Martian) who can tell me that with more credibility than a search on google. If you have nothing to contribute to a conversation, stay the fluff out.

Why is there no consensus on this? Do different countries use different definitions for trapezoid?

Anyway, what I was taught in dutch high school is that a trapezoid has at least one pair of parallel sides. So yes, a square is a trapezoid. And parallelograms are trapezoids too.

English majors aren't required to know enough math? probably has something to do with Colonials getting pissed off at British taxes. came into use circa 1706. don't remember where.
