Based on the above, the picture of a semi-regular tessellation is shown below.
What is semi-regular tessellation?
A semi-regular tessellation, also known as a uniform tessellation or Archimedean tessellation, is a geometric pattern formed by repeating two or more regular polygons in a symmetrical arrangement. Unlike regular tessellations, where only one type of polygon is used, semi-regular tessellations employ multiple polygonal shapes at each vertex.
Therefore, one can say that the arrangement ensures that the same combination of polygons meets at each vertex, creating a balanced and predictable pattern. Archimedean solids, such as the truncated octahedron or snub cube, exemplify semi-regular tessellations.
