Basic Triangle: Basic Disequilibrium 120 LCD Triangle:
"We cannot further subdivide the spherical icosahedron into right triangles, but we can in the planar icosahedron. When the sides of the triangle in the planar icosahedron are bisected four similar triangles result, and the process can be continued indefinitely. But in the spherical icosahedron, the smaller the triangle, the less the spherical excess, so the series of triangles will not be similar.
