## The Fractal Logic of ARTriangles

ARTriangles products are probably the most sophisticated mosaic tiling systems ever offered. In order to become familiar with the fractal symmetry embodied in these shapes, it is useful to perform a few basic manipulations. Based on the Golden or Divine Proportion, the acute triangle consists of two long sides and one short. The obtuse triangle has two short sides and one long. For the first exercise, arrange ten acute triangles into a circle. Next arrange ten obtuse triangle
