The geodesics intersect to form triangular elements, which have local, triangular rigidity, and so distribute the structural stress throughout the geodesic sphere.The design of a geodesic dome begins with an icosahedron (20-side form) inscribed within a hypothetical sphere. Each triangular face of the icosahedron is subdivided into n2 similar triangular tiles, n being the chosen degree of subdivision. The small triangles' vertices are then projected onto the sphere, carrying the arrangement of edges along with them.When fitted exactly, the sub-triangle edge-lengths assume different values, which thus requires links of many sizes to form the structure (spherical or hemispherical). To minimize the number of different values for the edge-lengths, the design is simplified, and the resultant geodesic dome is a compromise of triangles with the vertices lying approximately on the sphere, so that the triangle-edges form approximate geodesic paths over the surface of the geodesic dome."@en }
