Could someone describe to me how to find the angle between two intersecting pentagonal faces on a great dodecahedron? Thanks

    Doesn't a great dodecahedron have triangular faces? A regular dodecahedron has pentagonal faces...2011-12-02

    There is an illustrative discussion of a comment similar to that of @mjqxxxx above in *Proofs and refutations* by Imre Lakatos on pp. 16--17 and pp. 30--33.2011-12-02
