Homework Help: Platonic solids

    [SOLVED] platonic solids

    1. The problem statement, all variables and given/known data

    Let f_1 be a face of one tetrahedron and let f_2 be a face on a second same-sized tetrahedron. Why do you not get a sixth Platonic solid when you identify f_1 and f_2, which you can do because they are the same triangle?


    2. Relevant equations



    3. The attempt at a solution

    For a platonic solid, the same number of faces have to meet at each vertex.
