An octagon is a two-dimensional polygon with eight sides and eight angles. When discussing it in a 3D context, an octagon can be represented as a flat shape in three-dimensional space, such as the base of a prism or a pyramid. Alternatively, an octagonal prism or pyramid consists of octagonal faces combined with additional polygonal faces, creating a three-dimensional geometric object.
It looks like a 3D shape that has 9 sides (the cousin of an octogon).
