Trapezoids, etc.

According to Math is Fun, a trapezoid (called a trapezium in the UK) has a pair of opposite sides parallel. Most of the patterns here are isosceles trapezoids, meaning the sides aren't parallel, but they are equal in length, and both angles coming from a parallel side are equal. One parallelogram is also in this mix. Let us know if you need help deciding which it is. And, because it defies our abilities to put it into a neat category, there is one here that has six sides.
