Answer:
regular tessellation
Explanation:
A regular tessellation is a repeating pattern of congruent regular polygons on a plane with no gaps or overlaps.
Since a regular tessellation is with no gaps and overlaps, the only regular polygons that will tessellate are equilateral triangles, squares and regular hexagons. Therefore, there are only three types regular tessellations (ones made from squares, equilateral triangles and hexagons),
