What feature of a shape allows it to tesselate?
I don't have a general answer for you, but that is a good question ://
If any combination of its interior angle can add up to 360 deg, then it can tesselate :)
I am not sure about this, but if this is wrong, this is close already.(I think...)
Someone please help modify my statement.
I do not understand what you mean Max :/
Here is a pretty tesselation, what angles are you referring to?
