You cannot tessellate convex polygons with 7 or more sides.
True.
No convex polygon with 7 or more sides will tessellate.
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.
Yes, it is true that you cannot tessellate seven-sided regular polygons (heptagons) by themselves. This is because the interior angle of a regular heptagon is approximately 128.57 degrees, which does not divide evenly into 360 degrees. As a result, heptagons cannot fit together without leaving gaps or overlapping, thus preventing them from tessellating.
No because its angles are not factors of 360 degrees
No. Regular heptagons (seven sides) doesn't tessellate alone.
a heptagon is the only polygon that has seven sides
I would think that the obvious answer would be yes. maybe I am missing something in the question why would one think that you could not tile a seven sided polygon? * * * * * Yes, maybe you are missing something - mathematic reality. There are no polygons - regualr or irregular of 7 or more sides which will tessellate with identical shapes.
seven
Regular polygons with even sides if there are 6 or more of them; selected irregular polygons with seven or more odd numbers of sides.
All sorts. For starters, no convex polygon with more than six sides tessellates, and various polyominoes of seven or more squares don't.
The name for a 7-sided polygon is septagon, the root word "sept" meaning "seven".
