A tessellation is a tiling that repeats. ... There are only three regular shapes that tessellate – the square, the equilateral triangle, and the regular hexagon. All other regular shapes, like the regular pentagon and regular octagon, do not tessellate on their own.
Why do regular octagons not tessellate?
Why or why not? It is not possible to tile the plane using only octagons. Two octagons have angle measures that sum to 270° (135° + 135°), leaving a gap of 90°. Three octagons surrounding a point on the plane would have angle measures that sum to 405°, which would cause an overlap of 45°.
Can a regular quadrilateral tessellate?
Every shape of quadrilateral can be used to tessellate the plane. In both cases, the angle sum of the shape plays a key role. Since triangles have angle sum 180° and quadrilaterals have angle sum 360°, copies of one tile can fill out the 360° surrounding a vertex of the tessellation.
