### Quadrilateral

I have a quadrilateral but I don’t really know its name.

I only know diagonals have lengths that are the same.

Can you find the answer or is there more than one?

List the possibilities and start to have some fun!

If opposite sides are parallel, that’s both pairs you
may note,

The figure is rectangular – for that you’d have to vote!

If just one pair are parallel, your first guess will
be void.

Your figure is isosceles and it’s a trapezoid!
