An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. They can have faces which are triangles, quadrilaterals, pentagons, hexagons or heptagons.
There is non.
The equivalent of a octahedron as a 2D shape is an 8 sided octagon.
octagon-2D Octahedron-3D
The suffix "hedron" implies 3D. The 2D suffix is "gon"
Polygons are 2d shapes whereas polyhedrons are 3d shapes

A 2 dimensional shape (or a 2D shape) is a shape withe a length and height, in some other cases, like a circle or oval or irregular shapes are also 2D shapes. Conclusion: A 2D shape is a shape that only have one section, that can be drawn.
2D shapes include squares, triangles, rectangles and circles.
