The first characteristic is also the most complex: composition. The composition usually involves smaller geometric shapes that are repeated, creating rhythm. A grid of either equilateral triangles or squares is used as a foundation, but
sometimes a twist on the triangle grida hexagonal grid is used instead. Circles, squares, and straight lines provide the
basis for the pattern, which is interlaced, combined, and duplicated in order to create a beautiful design. In mathematics,
these grids of repeated figures are called tessellations, a word which is derived from the Latin word tessere, meaning
"pieces of mosaic." A tessellation repeats a polygon over and over to tile a plane.
