named quadrilaterals

I'm thinking of one of these shapes
you can ask me any questions but I can only reply "yes" or "no"

you can firmly identify my shape in at most three questions
what would your first question be?
are there alternatives?

can you string the eight special quadrilaterals in a line with just one difference between them?
