How many regular tessellations are there in math?Ī regular tessellation is a pattern made by repeating a regular polygon. The angles around each vertex are exactly the four angles of the original quadrilateral. Rotate by 180° about the midpoint of one of its sides, and then repeat using the midpoints of other sides to build up a tessellation. Begin with an arbitrary quadrilateral ABCD. How do you make a tessellation of a quadrilateral?Īll quadrilaterals tessellate. A regular polygon with more than six sides has a corner angle larger than 120° (which is 360°/3) and smaller than 180° (which is 360°/2) so it cannot evenly divide 360°. We have already seen that the regular pentagon does not tessellate. There is a regular tessellation using three hexagons around each vertex. This is not an integer, so tessellation is impossible.Ĭan You tessellate a pentagon with three hexagons? No other regular polygon can tessellate because of the angles of the corners of the polygons. One may also ask, can a 12 sided polygon Tessellate? Only three regular polygons tessellate: equilateral triangles, squares, and regular hexagons. Which regular polygons will tessellate on their own without any spaces or overlaps? Equilateral triangles, squares and regular hexagons are the only regular polygons that will tessellate.Ĭan a 12 sided polygon be used to tessellate? Would an octagon and equilateral triangle tessellate? Since there are no integers between three and four, pentagons must not tessellate. Since the interior angles get larger as the number of sides in a polygon gets larger, no regular polygons with more than six sides can tessellate by themselves. Can you tessellate six sided polygons by themselves? Three octagons surrounding a point on the plane would have angle measures that sum to 405°, which would cause an overlap of 45°. Two octagons have angle measures that sum to 270° (135° + 135°), leaving a gap of 90°. Why or why not? It is not possible to tile the plane using only octagons. All other regular shapes, like the regular pentagon and regular octagon, do not tessellate on their own. There are only three regular shapes that tessellate – the square, the equilateral triangle, and the regular hexagon. 6 How do you make a tessellation of a quadrilateral?Ī tessellation is a tiling that repeats. 5 Can You tessellate a pentagon with three hexagons?.4 Would an octagon and equilateral triangle tessellate?.3 Can you tessellate six sided polygons by themselves?.
