The cross (like the 'red cross') is a 4 pointed star.
The pentagram is a 5 pointed star with rotational symmetry.
The Islamic star is a 5 pointed star without rotational symmetry (has reflectional symmetry).
The hexagram is a 6 pointed star.
The octagram is an 8 pointed star (a bit like on the Union Jack).
Anyone have anything to add??
