The suffix "hedron" implies 3D.
The 2D suffix is "gon"

There is non.
The equivalent of a octahedron as a 2D shape is an 8 sided octagon.
A 3D diamond, often represented as a regular octahedron, has 12 edges. In geometric terms, a diamond shape can also refer to a rhombus in 2D, but in 3D, the octahedron is the closest representation of a diamond-like form. Each vertex of the octahedron connects to four others, contributing to the total edge count.
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.

As a 2D polygon shape it is an 8 sided octagon.
The equivalent of a octahedron as a 2D shape is an 8 sided octagon.
An eight-faced 3D shape is called an octahedron. Any 3D shape (polyhedron) ends in -hedron, just like any 2D shape (polygon) ends in -gon, and octa- means 8.
An octahedron is a 3D shape with 8 sides.
A camera is a 3D shape. A photograph is a 2D projection of a 3D shape onto a 2D shape.
A 'Quadrilateral' is a 2-dimensional, 4 sided polygon. The following names are quadriltaerals;- square, rectangle, rhombus, trapezium, parallelogram, kite, and an irrelgular qudarilateral. NB In 3-dimensional space, ther equivlanet is a 'CUBOID'.
A television set is a 3D shape. The image (picture) on the television screen is a 2D shape. 3D is when it has length, width, and height. 2D is only length and width.
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.
It's a 2D shape.
