An icosahedron is a 20-sided figure. It also has 30 edges.
It has 20 faces. The number of edges will depend on the exact configuration of the shape. For example, a icosahedron in the form of a prism, with 18-gons as bases, will have 54 edges. On the other hand a pyramid with a 19-gon base will have 38 edges. A bipyramid with a decagon base will have 30 edges. There are very many more possible shapes.
A regular icosahedron has 20 faces (equilateral triangles), 30 edges and 12 vertices.

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!
