 :According to the sources I've found (listed above), your assertion is the wrong way round. A pentagram is a five-pointed star, but a five-pointed star may or may not be a pentagram. for it to be a pentagram (from Greek pentagrammon ""of five lines"") it needs to be constructed of five lines only, each line crossing two others, so that a star of five points is formed, with a pentagon in the centre (). A star is simply ""A graphic design having five or more radiating points"" (www.dictionary.com) (although I would argue that you can have a four- or even three-point star as well). A five-point star may or may not have internal lines, or polka-dots, or whatever you want within it.  "
