Re: PARCC Definition of Trapezoid

Plain and simple.....the PAARC definition is wrong and should be corrected at that level. How do we bring it to their attention? Some teachers may not know any better and actually teach it that way. It's the same as saying that the sum of the angles of a triangle is "at least 180".

Subject PARCC Definition of 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.
