It is one of four nonconvex polyhedra with regular polygons or stars as … WebMay 9, 2015 · R 2 = 1 + ( R − a) 2. Solve that equation for R, and use the fact that you know a. The equation is not truly quadratic, since the R 2 terms cancel. Now you have the coordinates of the center and of two adjacent vertices, so you can find the cosine of the angle between the lines from the center to those vertices. Share.

WebThe rhombicuboctahedron is a rectified rhombic dodecahedron. Recall that rectification means extreme truncation. It creates new vertices mid-edge to the rhombic dodecahedron, creating rectangular faces inside the original rhombic faces, and new square and triangle faces at the original vertices. It is also an expanded cube or expanded octahedron. WebThe dodecahedron and icosahedron are dual polyhedra. A regular dodecahedron has 12 faces and 20 vertices, whereas a regular icosahedron has 20 faces and 12 vertices. Both have 30 edges. When a …
