A three-dimensional shape with eight triangular faces is called an octahedron.
It has eight faces, hence the name octagonal pyramid.
A truncated tetrahedron has eight 8 faces: 4 hexagonal faces and 4 triangular faces.
the faces of the hexagonal prism is eight triangular faces. Because of the ambiguity of the term octahedron and the dissimilarity of the various eight-sidedfigures,
trangular pirimad i think
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).
A triangular prism has three rectangular faces and two triangular faces.
A triangular prism, a triangle base and three triangular faces (a tetrahedron)The figures below do not strictly have a "base" but they are composed entirely of trianglesAn octohedron (eight sides)An isocahedron (20 identical equilateral triangular faces, 30 edges and 12 vertices)Any of a number of deformations of the above
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- :)
Nine; eight triangular faces which all meet at the apex and the base, which is in the shape of an octagon.
Octahedron. (i assume your talking about something three dimensional).
A triangular prism has two triangular faces and 3 rectangular faces
