True.
All sorts. For starters, no convex polygon with more than six sides tessellates, and various polyominoes of seven or more squares don't.
A regular heptagon has seven sides.
it has seven sides and must look like a regular hexagon
A 7-sided shape is called a heptagon and not a septagon because the names of polygons are derived from the Greek names for the numbers. The Greek for "seven" is "hepta" - thus a heptagon is a 7-sided figure. If the system for naming polygons had been based on the Latin names for numbers, then a 7-sided polygon might have been called a septagon, since the Latin word for "seven" is "septem," but Latin is not the basis for these names in English.
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.
No. Regular heptagons (seven sides) doesn't tessellate alone.
If the seven sides are all the same length , then it is a regular polygon. A seven sided polygon is named a 'HEPTAGON'. If the seven sides are regular then it can be named as a ' Regular Heptagon'.
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 seven sided polygons are known as "heptagons". Heptagons that have all side lengths the same are known as "regular heptagons".
Unit 15 Section 3 : SymmetrySymmetries in regular polygons (http://www.cimt.plymouth.ac.uk/projects/mepres/book8/bk8i15/bk8_15i3.htm)Look at the regular heptagon below. A heptagon is a shape with seven sides and this one has equal sides and equal angles. You can see that there are seven lines of symmetry, and the regular heptagon also has rotational symmetry order seven.
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.
