Yes, that is what I was asking.
I interpreted Cynthia's question (and your original answer) as dealing with the
question of whether *all* quadrilaterals have the property.(It seemed to me that
your answer was proving this false by providing some examples of
nontrapezoids which do not have the property  which does not prove that
there are no examples of nontrapezoids that do have the property)

P.S. Of course I may have misread you  it is easy to get confused when the
negation of "any X is Y" is not the same as "there is not any X that is Y"
