Because the sum of where the vertices meet is 270°. The sum of where the vertices meet needs to be 360° in order for it to tile.
A plane figure with eight sides is an octagon.
No.
An octagon is a plane shape with just one face - an octagonal face! It cannot have triangular faces.
It's called an Octagon.
Not by itself.
No because when u tile an octogon it doesn't have a measure for a square
A regular octagon cannot tile a flat surface, it needs squares as fillers. An irregular octagon can tile a flat surface alone.
Well, if you take the regular octagon on the plane, security will likely confiscate it before you can board. The consequences are 8-10 years in prison. Now if you were to successfully get the regular octagon onto the plane, would it tile the plan? This depends on what type of tile you're talking about. A wooden tile can most definitely be achieved, and I've heard rumor that marble tiles are a difficult, yet feasible task. On the other hand, a porcelain tile has yet to be done, and I assume it to be impossible, along with most mosaic and vinyl tiles. If you find differently, please let me know. * * * * * Oh, that's so funny! To answer to the question: Not on its own.
No, but an octagon is.
yes
Yes it can. A regular octagon cannot.
yes
Yes.
An 8-sided plane figure is an octagon.
it can in accompaniment with squares.
No. You will have smaller square or triangular gaps between them.
