WebA polyhedron with all triangular faces can be a tetrahedron, an octahedron, or an icosahedron, among others. Let's sketch an octahedron, which has 8 faces, all of which are equilateral triangles. The octahedron has 6 vertices and 12 edges, and each edge is 2 times the length of the triangles' sides. WebWarm-up. In this warm-up, students analyze examples and counterexamples of polyhedra, observe their defining characteristics, and use their insights to sort objects into polyhedra and non-polyhedra. They then start developing a working definition of polyhedron. Prepare physical examples of polyhedra and non-polyhedra for students to sort.
