Eric W. Weisstein. "Kite." From MathWorldA Wolfram Web Resource.

My current book (McDougal LittellGeometry Applying, Reasoning and
Measuring)says opposite sides must be different.
I don't think it should be necessary for the opposite sides to be different.
This is another example of great discussion in math class.
I like to discuss concepts to show that math is not just a bunch of rules that
never evolve. We talk about the relative newness of fractal geometry, the many
ways we do proof now that we didn't do when I went to high school in the 60's.
