![]() ![]() The underlying pattern of this tiling is just a grid. I guess even though these shapes have eight sides each, they’re really just parallelograms or rectangles in disguise. You can’t tile the Euclidean plane with regular octagons. Only three regular polygons (shapes with all sides and angles equal) can form a tessellation by themselves- triangles, squares, and hexagons. Not only do they not have angles, but you can clearly see that it is impossible to put a series of circles next to each other without a gap. What shapes Cannot tessellate?Ĭircles or ovals, for example, cannot tessellate. From this, we know that a regular octagon will not tessellate by itself because 135? does not go evenly into 360?. ![]() Why a regular octagon does not tessellate?Įach angle in a regular pentagon is 1080?÷8=135?. Two octagons have angle measures that sum to 270° (135° + 135°), leaving a gap of 90°. It is not possible to tile the plane using only octagons.
