Vertices or a vertex is the technical term used in geometry for the corner points of a solid shape. A corner might refer to the point on the shape, but then it might also refer to the corners of the faces that make up the shape. The number of vertices can be worked out simply by counting or by using Euler's formula. Circle each with a pencil as you count it to avoid counting any twice.
Check the entire shape to make sure all the vertices have been counted. Rearrange Euler's formula to calculate the number of vertices in any Platonic solid, tetrahedron, cube, octahedron, dodecahedron, icosahedron.
