That is 'tessellation'
It is a pattern in which the tessera - individual tiles - need to be placed so as to cover a plane without gaps or overlaps.
No, it is using multiple copies of a shape, usually polygons, so as to cover a plane without gaps or overlaps.
the answer is yes
No spaces or overlaps exist between it's pieces.
No, it is not true that you cannot tessellate a six-sided polygon by itself. Hexagons are a type of polygon that can tessellate, which means they can be arranged in a repeating pattern to completely cover a plane without any gaps or overlaps.
"Tessellated" means to fit together closely, typically in a repeated pattern to cover a surface without any gaps or overlaps. It is often used in reference to geometric shapes or patterns.
No, there would be triangles in between. Sorry!
I would say that it overlaps but one can be moral without religion.
Yes, provided they fill the plane without gaps or overlaps.
It is a regular tessellation.
