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".

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.
