Regular tessellations of the plane by two or more convex regular polygons such that the same polygons in the same order surround each polygon vertex are called semiregular tessellations, or sometimes Archimedean tessellations.

How do you know if a tessellation is semi-regular?

Semi-Regular Tessellations

A semi-regular tessellation is made up of two or more regular polygons that are arranged the same at every vertex, which is just a fancy math name for a corner. A regular polygon is a polygon where all the sides and angles are the same.

What shapes make up a semi-regular tessellation?

Semi-Regular Tessellations

They comprise different combinations of equilateral triangles, squares, hexagons, octagons, and dodecagons. Each tessellation is named for the number of sides surrounding each vertex. These tessellations are named according to the number of sides of the shapes surrounding the vertex.
