Icosidodecahedron

An icosidodecahedron is a Archimedean solid comprised of twenty triangular faces, twelve pentagonal faces, 30 vertices and 60 edges. Every edge is connected with exactly one pentagon and one triangle, and each vertex is connected with two of each. It is a very challenging model to construct.

Tab and fold lines are available on the model but can be hidden if you do not want them. The outline is always present, but can be minimized to a very thin, light line so that it does not show up on the physical model. A small preview of the model also appears on the sheet, but you may want to hide this if you think it gives away too much to the student.
