A hexagon
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.
if its 2D its a octagon, if its 3D its a octagonal prisim
in 2D, a heptagon in 3D, a heptahedron
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.
