TEACHING AIDS FOR A REGULAR POLYHEDRON STUDY

摘要

The present invention relates to a regular polyhedral learning precinct, the skeleton coupled in a state in which the plurality of plate (13, 14, 15, 16) is orthogonal to each other is installed tightly inside the regular polyhedron (10). By the skeleton there are various lines and faces connecting the respective faces of the regular polyhedron 10 in the internal space of the regular polyhedron 10, and the internal space is divided into a plurality. Therefore, in addition to observing the appearance of the regular polyhedron, the regular polyhedron can be studied in more various ways by considering the internal space and finding the distance between arbitrary vertices, the volume of the regular polyhedron, the volume of each divided space, and the like.
