What kinds of regular polygons can be used for rgular tessellations?

Regular tessellations can be formed using only three types of regular polygons: equilateral triangles, squares, and regular hexagons. These shapes can fill a plane without any gaps or overlaps due to their angles and symmetry. Triangles have internal angles of 60 degrees, squares have 90 degrees, and hexagons have 120 degrees, all of which allow for perfect tiling. Other regular polygons, like pentagons or heptagons, cannot tessellate the plane on their own.
