Truncated Tetrahedron
Properties of the truncated tetrahedron: Number of faces, edges and dihedral angle measure
The truncated tetrahedron is created by truncating (cutting off) the tips of the tetrahedron one third of the way into each edge
8 total faces:
4 equilateral triangles and 4 regular hexagons
12 vertices:
2 hexagons and 1 triangle
18 edges
Dihedral angles:
70 degrees, 32 minutes for the hex-hex angle,
109 degrees, 28 minutes for the hex-tri angle
