text: It is listed under compound polyhedron and Uniform polyhedron compound and is NOT a polyhedron, just like a hexagram isn't a polygon, but rather two polygons (triangles).
text: Some common polygons are the triangle (with three sides), the quadrilateral (with four sides), the pentagon (with five sides), the hexagon (with six sides), the heptagon (with seven sides), and the octagon (with eight sides).

text: In the case of a tetrahedron, the polygons are all triangles by default, because in order to create a three-dimensional object with four polygons, each polygon must have three sides to connect with the other three polygons.
text: The polygons shown here are triangles, but they could have any number of sides.
