REGULAR POLYHEDRON SET FOR USE IN EDUCATION OF MATHEMATICS AND GEOMETRY

摘要

PROBLEM TO BE SOLVED: To solve the following problem: heretofore regular polyhedrons are only individually described and their correlations are rarely referred to.;SOLUTION: This regular polyhedron set is so constituted that transparent plastic regular polyhedrons are combined in the order of a regular icosahedron (small), a regular octahedron, a regular tetrahedron, a regular hexahedron, a regular dodecahedron, a regular icosahedron (large), and a table of the data such as the length of their edges is attached.;COPYRIGHT: (C)2005,JPO&NCIPI
