Parallelogram

A parallelogram is a 2 dimensional box bounded by 2 sets of equal length opposing lines, but the each set is not necessarily the same length as the other set and the angles are not necessarily right angles. If all the angles are right angles, then it is a type of parallelogram called a rectangle. If all 4 sides are equal length, then it is a square. If the angles are definitely not right angles, then the parallelogram is called a rhombus. The pendant pictured above is a rhombus.
The idea of the parallelogram was known to the ancient Greeks (perhaps earlier). The ancient Greek mathematician wrote about it.
You can find the pendant pictured above as well as other jewelry pieces on Metal Jewelry Shaper.
