Abstract
The polyhedron globe puzzle system of this invention comprises a plurality of scalene triangles with attachment means so as to form a generally spherical body on which is inscribed a world map such that the position of the scalene triangles contains latent and patent information and intelligence about the geography of the world map including but not limited to longitudinal and latitudinal information. The 360 edges of the 240'dron form themselves into 21 circumscribing polygons which, when projected on to a concentric true sphere, become Great Circles.
Claims1
A polyhedron globe educational system comprising:
- a) a plurality of 240 scalene triangles;
- b) means for interconnecting said plurality of scalene triangles, connected to form a generally spherical globe;
- c) a world map inscribed on said generally spherical globe;
- d) wherein the edges of said plurality of scalene triangles represent a section of a Great Circle of said world map on said globe;
- e) said means for interconnecting said 240 scalene triangles comprise a plurality of perforated lugs and matching studs connected to said 240 scalene triangles and wherein said 240 scalene triangles meet over one of said plurality of lugs and wherein plurality of said lugs are inter connected together to form said polyhedron globe including a means for gleaning geographical information from said polyhedron globe;
- and
- f) wherein said 240 scalene triangles are 60 each of four different types interconnected with said plurality of lugs which are also of 4 different types corresponding to 10, 8, 6 and 4 way junctions.
