6. Pyramid without tops 3D paper model // The truncated tetrahedron

For truncated tetrahedron, you may obtain a very effective colour arrangement by using the same four colours for the hexagons that you used for the triangles in the tetrahedron. Then the triangles here may all be of a fifth colour.

Way to make the model is simply to make a tetrahedral cup. This has a triangular bottom and three hexagons for sides. The tabs form ribs on the inside of the cup. Then you continue by cementing triangles and hexagons as needed.

You will find it best to use a triangle as the last part and to cement one of the tabs of this triangle, first letting it set up firmly, and then closing the hole as you would close the lid on a box. This is a general procedure to follow for all models.

Thank you
Now I understood how truncated tetrahedral has 4hexagonal and 4 triangular faces
