As part of our creative hands-on math studies we have been studying icosahedrons. Icosahedrons are 20 sided three-dimensional solid figures. When the faces of solid figures protrude to form more complex solids, the shapes become star-like and are known as stellations. The icosahedron we created is the small triambic icosahedron, also known as the first stellation of the icosahedron.
This video tutorial on how to construct a small triambic icosahedron.
