How many corners has a icosahedron have?

The name most mathematicians use for the corners is vertices. An icosahedron is a 20 sided polyhedron. It is one of a group of special solids known as platonic solids. So, the icosahedron has 20 faces and 12 vertices or "corners" as you call them. It has 30 edges. There is an interesting formula that relates the number of edges, vertices and faces. V+F-2=E where V is the number of vertices, F the number of faces, and E the number of edges. In the case of the icosahedron we have 12+20-2=12+18=30 just as we expected. The nice thing about the formula is if you know two of these things, you can always find the third!
