Hi Allan

You might be interested in visiting this link on my website where I suggest ideas by using dynamic transformations to develop understanding of inclusive classification informally BEFORE introducing definitions:
http://math.kennesaw.edu/~mdevilli/quadclassify.html

You might also be interested in this extended classification of quadrilaterals
http://mysite.mweb.co.za/residents/profmd/quadclassify.pdf
which is an excerpt from my book "Some Adventures in Euclidean Geometry", which discusses quite extensively why inclusive definitions of quadrilaterals are more useful than exclusive ones. For more info go to:

Hope that helps.

Regards
Michael
