Hmmmm... what if you use the British interpretation ? here 'trapezoid' is defined as a quadrilateral with no sides parallel and a 'trapezium' is a quadrilateral with one pair of parallel sides?
Food for thought as we grapple over inclusive v. exclusive ?US? definitions of the term trapezoid?

I've been reviewing recently released PARCC documents and was confused that PARCC is defining a trapezoid as having "at least one pair of parallel sides". However, the most recent definition I can find issued by NYS is in the 2005 Standards math glossary, in which a trapezoid is defined as having exactly one pair of parallel sides. Since this will impact instruction from Grade 3 on, I'm curious is anyone else is aware of this issue, or any discussions surrounding it.
