A circle!
answer
All shapes have to be polygons, because there is no shape that has 1 or 2 sides. A tessellation has to be a shape, so that it can be repeated. Its not going to be much of a tessellation if its a line.. lol.. that isn't a tessellation
A pure tessellation is a tiling of a plane using one single type of regular polygon, such as triangles, squares, or hexagons, without any gaps or overlaps. The polygons fit together perfectly to cover the entire plane, creating a repeating pattern that extends infinitely in all directions. Pure tessellations are often found in art, architecture, and mathematics due to their aesthetic appeal and mathematical properties.
equilateral triangle
false, there would be gaps.
Tessellation is using multiple copies of a shape, usually a polygon, to cover a plane without gaps or overlaps. Each copy of this single shape is a tessellating unit.
No a pentagon is a single polygonal shape, A tessellation is a scheme for covering a plane, without gaps of overlaps, using multiple copies of the same basic shape. These are usually polygons.
A regular tessellation is based on only one regular polygonal shape. A semi-regular tessellation is based on two or more regular polygons.
A tessellation is created when a shape is repeated over and over again covering a plane without any gaps or overlaps.
regular hexagon
Tessellation is covering a 2-d surface. Tessellation and making a 3-d shape are not compatible processes. 12 regular pentagons will form a dodecahedron.
