There are two objects, one convex and one nonconvex, that can both be called regular icosahedra. Each has 30 edges and 20 equilateral triangle faces with five meeting at each of its twelve vertices. Both have icosahedral symmetry. The term "regular icosahedron" generally refers to the convex variety, while the nonconvex form is called a great icosahedron. WebThe Kepler-Poinsot solids, illustrated above, are known as the Great Dodecahedron, Great Icosahedron, Great Stellated Dodecahedron, and Small Stellated Dodecahedron. Cauchy (1813) proved that these four exhaust all possibilities for …

The intersections of the triangles do not represent new edges. flink clickhouse etl

Cut out 20 equilateral triangles from thick paper. The bigger your triangles the bigger your final icosahedron. Try and make all your triangles exactly the same; making and using a template is good idea. The more uniform your triangles the better your final icosahedron will fit together. flink clickhouse github
