The Parallelogram and teenage fantasies.

Parallelograms, what's not to like? They are uncomplicated, formulaic, friendly and above all, they are the kind of geometric shape who's properties you will never forget. Why? Because apart from struggling with the awkward spelling trauma caused by trying to figure out just how to write down parallelepiped (motherf****r), the ortography of the 2 dimensional parallel "brother-form" would equally drive you up the wall in high school. Double 'l', twice or just once?

Okay, so it wasn't love at first sight, but there was something mystical that drew my attention to the unusual square. This is when I decided to give myself a mission, after all those years of soul searching and trying to find the true meaning of life, I decided I was going to finally do it, I was going to Google the parallelogram.

(Dramatic pause.)

I discovered there are four types of parallelograms, I discovered its area to be equal to A = A_\text{rect} - 2 \times A_\text{tri} = \left( (B+A) \times H \right) - \left( A \times H \right) = B \times H.\,

but most of all, I discovered I was not alone.

Yes, young girls and boys, there is a world of geeks out there and they all hail our parallel friend.

So here is my question, if the parallelogram fails to have 90 degree angles and looks like a square who's had a bad episode with a large bottle of Jack Daniels, what came first, the rectangle or the parallelogram?

Please find below a late seventies sci-fi movie, 'Deamon Seed' about a bronze speaking evil monster made up entirely out of parallelograms. I think I just wet myself.

P.S.: The big bird picture, not completely irrelevant.
