True * * * * * No. The only regular polygons that will tessellate are a triangle, a square and a heagon. So a regular heptagon will not tessellate.
No.
no
No.
No. Regular heptagons (seven sides) doesn't tessellate alone.
No.
There is no such polygon.
The heptagon (7 sided polygon) cannot tessellate. The exterior angle of the heptagon is 51.43 degrees which makes the interior angle 128.57 degrees.
No convex polygon with 7 or more sides can tessellate.
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!
There are decagons which will tessellate.
No cones can not tessellate.
