Best Answer

An icosahedron has 20 faces, 30 edges, and 12 vertexes. 5 polygons meet at each vertex and each face has 3 vertexes (therefore made of triangles).

A dodecahedron has 12 faces, 30 edges, and 20 vertexes. 3 polygons meet at each vertex and each face has 5 vertexes (therefore made of pentagons).

How many angles does an icosahedron have?

An icosahedron is named after the number of faces that it has. The number of vertices 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 36 vertices. A pyramid with a 19-gon base will have 20 vertices. A bipyramid with a decagon base will have 12 vertices. There are very many more possible shapes.
