Agreed...I see what you're saying now... You would have preferred the question said The quadrilateral could be and then the choices. Liz Waite

There's clearly a best answer. I didn't mean to raise it as a grading issue. It is, rather, a quality issue.
I am concerned that this is yet again a poorly written question. They've chosen what reads like universal language, but intended that it apply to a particular example.
And this is in a geometry course, the primary place in secondary mathematics where the distinctions between "all" and "some" and between "always," "sometimes," and "never" are taught and reinforced.

It could be an isosceles trapezoid, but that's not the question as asked. We really should be expecting mathematically precise language.

Right...but were you saying that out of the 4 choices none were correct? Liz

In a kite, neither pair of sides is parallel.

I believe isosceles trapezoid is correct. Although I do recall an earlier conversation on this list from several years ago where a few people defined a trapezoid as a quadrilateral with AT LEAST one pair of parallel sides where most of us used EXACTLY one pair of parallel sides. This would make a difference, I think. Liz Waite

The diagonals of a quadrilateral are congruent but do not bisect eac other. The quadrilateral is:
Iso trapezoid Parallelogram Rectangle Rhombus
But none of these are necessarily correct (kite, anyone?)

Hi All Sorry this is a bit late, but I have been away for the last week. I hope you are all enjoying some time off over the summer. I know most of you have seen the news around the release of the PARCC Model Content Frameworks for public comment. For those of you who have not, read on. · The Model Content Frameworks in Mathematics and English language arts/literacy were released for public review on August 3rd, after several rounds of feedback from the PARCC states. This public review period is an opportunity for an even wider group of interested parties to provide feedback on all parts of the frameworks, including the introductions and the grade level analyses, which contain suggested areas of emphasis and priority. · By following the this link, http://www.parcconline.org/parcccontentframeworks, you will be able to review the draft Model Content Frameworks and provide your feedback through an online survey. All feedback is due to PARCC by Wednesday, August 17th. During this public review period, PARCC hopes that teachers in particular will provide their feedback on the draft Model Content Frameworks. While teachers have helped to develop the frameworks to this point, the feedback of a broader group of educators is critical. The Model Content Frameworks are being shared directly with NCTM, NCSM, NCTE, AFT, and NEA, as well as others, so these organizations can share them with their members, as well. · John Svendsen Mathematics Associate Office of Curriculum and Instruction NYS Education Department EB 320 Albany, N.Y. 12234 (518) 4745922 (518) 4861385 (fax) jsvendse@mail.nysed.gov http://www.emsc.nysed.gov/ciai/mst/math/home.html www.emsc.nysed.gov/ciai
