Making Dice, Part 2 (Posted on 2003-04-17) Difficulty: 3 of 5
My friend finished making dodecahedrons, and her next project is to make regular icosahedrons (20-sided dice). Again she wants to know: what is the dihedral angle between any two adjacent faces?

Perhaps this can be solved without the use of spherical trig? ;P
