A friend at work asked me to calculate the central angle of a regular dodecahedron. I think he was trying to stump me. Just to be sure we are talking the same thing, he was referring to the angle between any two radii drawn from a vertex of the dodecahedron to the center.(adsbygoogle = window.adsbygoogle || []).push({});

At any rate, I did a quick calculation and came up with two answers: 180 degrees and 52.44 degrees. Before I present him with these answers, I just want to check - am I anywhere near close?
