WebThe octahedron is a Platonic solid, which has all its faces with a triangular shape. An octahedron has 8 triangular faces, 12 edges, and 6 vertices. These figures have the shape of a double square pyramid. Each of the faces of the octahedron meets three other faces. Also, four faces meet at each vertex. WebJul 15, 2024 · Each face of the tetrahedron is opposite a parallel face, so we can group its 8 faces into 4 groups of 2 parallel planes. Each group of two parallel planes divides space into 3 regions, one in between and two on either side. So, all 4 groups divide space into at most 3 4 = 81 regions. We'll figure out which combinations are present.
