A tiling
... All the same kinds of polygons are used in one particular tiling. Each tile is arranged in the same order, meeting at each vertex. Monohedral tiling – Tiling that uses only one size and shape of tile. Regular tiling – Monohedral tiling that uses regular polygons. Edge-to-edge tiling – The ...
