An octahedron can have any number from 6 to 12 vertices.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. In most cases there will be no verticals.
Either no verticals or two verticals and two horizontals.
Verticals are corners so in a two dimensional a square has 4 verticals
3 angles 3 verticals
A tetrahedron need not have any verticals.
An octahedron has 8 sides.
An octahedron has 18 corners.
a octahedron has 8 faces
An octahedron has eight faces - by definition.
In geometry, an octahedron is a polyhedron with eightfaces.
An octahedron has eight bases/faces.
An octahedron has 8 sides.An octahedron is a polyhedron with eight plane faces.
An octahedron has eight faces. If it has 62 faces then it is not an octahedron!
