A hexagon
A 2D shape does have one face.
Icosagon
a 2d shape can only ever contain 1 face!
No. A 2d shape is a plane area, which may be regarded as a face, which is bounded by a side or sides.
I think they all have 1.... because 2d shapes are flat!!! :)
An icosahedron is a polyhedron has 20 faces, and is a 3D shape.
A hexagon is a 2D shape so it doesn't have faces or edges. It has 6 sides and 6 vertices.
Such a 2D shape is a hexagon, a six sided figure.
if its 2D its a octagon, if its 3D its a octagonal prisim
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.
A rhomboid kind of comes from a rhombus. A rhombus Is a 2d shape. The rhomboid has been enlarged from a rhombus so now that it has space inside it which is called volume. There are 6 faces.
Only one; a triangle is a 2D shape, not a 3D shape. Usually only 3D (or more) shapes are considered to have 'faces'.
