An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The number of triangles will depend on which one of the 257 shapes you have in mind:All 8 faces of a quadrilateral based bipyramid will be triangles.A heptagon based pyramid has 7 triangular faces.A hexagonal prism has none.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octahedron can have triangles for all eight faces or, as is the case with a hexagonal prism, not a single triangular face.
One difference: An octahedron has 8 faces, a triangular prism has 5. An octahedron (="eight faces") is a regular high-symmetry solid with all the faces identical. A triangular prism has a triangular base, a triangular roof, and 3 rectangular sides (walls).
There are 5. They are the tetrahedron (4 triangular faces), the cube (6 square faces), the octahedron (8 triangular faces), the dodecahedron (12 pentagonal faces), and the icosahedron (20 triangular faces).
A Hexahedron has no triangular faces. A Tetrahedron has 4 triangular faces. A octahedron has 8 triangular faces. A Icosahedron has 20 triangular faces. By:-Cherrylvr- :)
yes it does, but it can again be drown in a way it doesn't

An octahedron: two quadrilateral based pyramids with their bases together.

An ordinary octahedron with 8 triangular faces has 6 vertices.
A tetrahedron is one such, so is an octahedron.

There are many possible shapes. The regular ones amongst them are the tetrahedron, the octahedron and the icosahedron.
