A regular heptagon does not tessellate because its internal angle is approximately 128.57 degrees, which does not divide evenly into 360 degrees. For a shape to tessellate, the angles must combine perfectly to fill the space around a point without gaps or overlaps. Since the angles of a heptagon cannot satisfy this requirement, they cannot create a repeating pattern that covers a plane without leaving empty spaces.

Equilateral triangle, square and regular hexagon.
No. Equilateral heptagons (7 sided figures) do not tessellate the plane. Not if no other polygons are allowed. But if you allow a (non-equilateral) pentagon then you might be able to tessellate the plane!

Regular heptagons cannot tessellate the plane. This is because the interior angle of a regular heptagon is approximately 128.57 degrees, and when you attempt to fit these angles together at a point, they do not sum to 360 degrees. Therefore, it's impossible to create a repeating pattern with regular heptagons that fills a space without gaps or overlaps.
A regular octagon can tessellate the plane when combined with regular squares. By placing a square in the center of the octagon and surrounding it with eight octagons, the shapes can be repeated infinitely, filling the plane without gaps or overlaps
The three regular polygons that can tessellate in a plane are equilateral triangles, squares, and regular hexagons. These shapes can fill a space without any gaps or overlaps because their interior angles are divisors of 360 degrees. Equilateral triangles have angles of 60 degrees, squares have angles of 90 degrees, and regular hexagons have angles of 120 degrees, all of which allow for complete tiling of the plane.
