Each face is what polygon on a octahedron?
A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
Why is a truncated octahedron called a truncated octahedron?
Start with an octahedron in the form of a quadrilateral based dipyramid a regular octahedron is a special case of this). This shape has six vertices - chop these off so as to remove a quadrilateral based pyramid. You will be left with a truncated octahedron. It is an octahedron which has been truncated (shortened) by cutting off its extremities.
