An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. They can have faces/bases which are triangles, quadrilaterals, pentagons, hexagons or heptagons.

What is the base shape of the octahedron?
It can be a heptagon (heptagonal pyramid), hexagon (hexagonal prism), square (square based bipyramid). There are versions with pentagonal or triangular bases but I cannot think of their names.
How many faces does an octahedron have?
An octahedron has 8 sides.An octahedron is a polyhedron with eight plane faces.
How many sides does an octahedron have?
An octahedron has 8 sides.
How many faces has a octahedron?
a octahedron has 8 faces
What is a octahedron solid?
An octahedron is a 3D shape with 8 sides.
What has a base with 8 equal sides 8 faces that are triangles?
The answer to your question, is an Octahedron.
Is a octahedron a pyramid?
It can be but need not be. A heptagon-based pyramid is an octahedron. However, the term is often used for the Platonic solid bounded by eight equilateral triangles - in the form of two square based pyramids stuck together base-to-base.
What other shape has the same base as a triangular prism?
A regular tetrahedron. octahedron, dodecahedron.
What is the base of a octahedron?
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.
What octahedron triangle for all their faces?
A regular octahedron is a Platonic solid with equilateral triangles for each of the faces. A heptagonal pyramid is an octahedron with one heptagon (a seven sided figure) as its base and 7 triangles, one attached to each side, meeting at the either vertex.
If a triangle that Has a base with 8 equal sides and all faces are triangles what is it?
This object is called an octahedron
What shape is the base of an octahedron?
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The various octahedra have faces which may be triangles, quadrilaterals, pentagons, hexagons or heptagons. Any one of these could be a base.
How do you make a 3D octahedron?
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The simplest octahedron to make is probably the heptagon based right pyramid. The net for this shape is a regular heptagon with seven identical triangles attached to its edges. If the triangles are folded to meet at a point above the heptagonal base you will have an octahedron.
What is the base shape of the octahedron?
It can be a heptagon (heptagonal pyramid), hexagon (hexagonal prism), square (square based bipyramid). There are versions with pentagonal or triangular bases but I cannot think of their names.
What polyhedron has a base of a triangle?
A tetrahedron, a triangle based pyramid, an octahedron, an icosahedron plus many more.
What is the difference between a octahedron and a triangular prism?
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).
Name of a 3D shape with 8 sides?
hexagonal prism In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has 8 faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces. https://en.wikipedia.org/wiki/Hexagonal_prism#/media/File:Hexagonal_prism.png
