Tetrahedron a regular Platonic Solid
1963-1965
Selection of 62 uniform polyhedron models, including 5 Platonic solids, 4 Kepler-Poinsot solids, 43 non-convex solids and 10 non-convex snub solids made of coloured card by Mr R. Buckley, c.1965.
All of he faces of these objects are regular polygons and in any one of the solids, all the corners are alike (vertices are congruent).
Apart from an infinite number of prisms and anti-prisms, only 75 different solid shapes can be constructed conforming with these conditions. They are called the 'uniform polyhedra'.
A regular polygon is a plane figure with all its sides equal and with equal angles between the sides. This definition includes the pentagram and pentagon.
Besides allowing the sides of the polygons to surround their centre more than once, the faces of the uniform polyhedra may surround the vertices more than once. As a result, the faces cross one another and in most of the models only parts of the faces show on the outside of the solids. For ease in identification, faces of any one kind on each model are the same colour.
