Title: Sectional toy block

Abstract: Toy blocks capable of being associated to form an assembly are provided. Each block has first and second juxtaposed portions of generally triangular shape with complementary hypotenuse faces facing in opposite directions. All the other faces of the block are planar. When the hypotenuse faces of one block are interfitted with the hypotenuse faces of a second block, a polyhedron, such as a cube, can be formed. Various other assemblies can be produced and the side faces ornamented as desired.
