**Truncated Dodecahedron **

## This polyhedron will be made from decagons and triangles. You will need 6 colors for the decagons and one color for the triangles.

## You will need to prepare 12 of the faces with the decagon template. Make 2 decagons of each color. You will then need 20 same-colored triangle faces.

## You can assemble this polyhedron by attaching 3 decagonal faces to one of the triangles. The 10 edges of each decagonal face will be glued alternately to a triangle and then to another decagonal face. All of the triangle faces will be surrounded by decagons.

## Beginning at the bottom of the polyhedron, you should be able to add the next appropriate face according to the rule above ... surround each triangle with 3 decagons and alternate decagons and triangles around each decagon. Continue adding faces in this manner until your polyhedron has closed at the top.
