josdavi Posted September 3, 2002 Report Share Posted September 3, 2002 Please teach me how to prove that (as shown below): Connect 20 Regular Octahedron (8-face solid) units together with exposing 4 faces per unit, forming a ball-shape article, this article will enclose a Regular Icosahedron (20-face solid) inside. Thank you. Link to comment Share on other sites More sharing options...
Captain Obvious Posted October 6, 2002 Report Share Posted October 6, 2002 While I can easily picture the 6 piece pole constructs, I cannot picture the 8 piece equatorial ring. Am I being short sited? Or is an Octohedron required to have 60 and 120 degree sides? Link to comment Share on other sites More sharing options...
