An octahedron is made up of how many triangles?

Answer 1

Oh, dude, an octahedron is made up of 8 triangles. Yeah, like, imagine a stop sign, but in 3D and with triangles instead of sides. So, if you're ever in a geometry showdown and someone asks you how many triangles are in an octahedron, you can confidently say 8 and totally impress them.

Answer 2

An octahedron is a polyhedron with eight faces, each of which is an equilateral triangle. Therefore, an octahedron is made up of a total of eight equilateral triangles. Each face of the octahedron is a triangular pyramid, resulting in a total of eight triangular faces.

Answer 3

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.
