'Chirality' of a certain form means that it is not super-imposable on its mirror image. Most of the regular and semi-regular polyhedra have identical original and mirror images but there are two that have a mirror image that is different. This means that they have a left-handed and a right- handed version. These two polyhedra are the so-called 'snub solids', the snub cube and the snub dodecahedron, that consist of a number of triangles and a number of either squares or pentagons respectively.
