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 grid-a 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.
