Triple goddess

The points on the star also refer to the five elements (Earth, Air, Fire, Water and Spirit). Sorry I can’t give moreww info, I don’t really know how to phrase it. (trust me on the little info I’ve given though, I’m Pagan/Wiccan a mix of both really)

The five pointed star is also associated with the tetragrammaton - my favorite google YHVH … the history and meaning is as follows : The pentagram symbol today is ascribed many meanings and deep significance, though much of this is very recent. However, it has been used throughout history and in many contexts:

  The earliest known use of the pentagram dates back to around
   3500BC at your of the Chaldees in Ancient Mesopotamia where it was
   symbolic of imperial power.
 Amongst the Hebrews, the symbol was ascribed to Truth and to the
   five books of the Pentateuch. It is sometimes, incorrectly, called
   the Seal of Solomon (see Hexagram).
  In Ancient Greece, it was called the Pentalpha, being
   geometrically composed of five A's. Unlike earlier civilizations,
   the Greeks did not generally attribute other symbolic meanings to
   the letters of their alphabet, but certain symbols became
   connected with Greek letter shapes or positions (eg Gammadion,
   Alpha-Omega).
 To the Gnostics, the pentagram was the 'Blazing Star'.
  For the Druids, it was a symbol of Godhead.
 In Egypt, it was a symbol of the 'underground womb'.
 The Pagan Celts ascribed the pentagram to the underground goddess
   Morrigan.
  Medieval Christians attributed the pentagram to the Five Wounds of
   Christ.
 * The Christian Emperor Constantine I used the pentagram, together
   with the chi-rho symbol in his seal and amulet. 
   In the legend of Sir Gawain and the Green Knight, the pentagram
   was Sir Gawain's glyph, inscribed in gold on his shield,
   symbolizing the five knightly virtues.
  In Medieval times, the 'Endless Knot' was a symbol of Truth and
   was a protection against demons. It was used as personal
   protection and to guard windows and doors.
  The pentagram with one point upwards symbolized summer; with two
   points upwards, it was a sign for winter.

      And During the long period of the Inquisition, the pentagram was
        seen to symbolize a Goat's Head. In the purge on witches, the
        horned god Pan became equated with the Devil (a Christian
        concept) and the pentagram, for the first time in history
        became a symbol of 'evil' and was called the Witch's Foot.

 with the emergence of Hermeticism, graphical symbolism became very
   important. The concept of the microcosmic world of Man as
   analogous to the macrocosm, the greater universe of spirit and
   elemental matter is a part of traditional occult teaching in both
   western and eastern philosophies. "As above, so below."
   The pentagram, the 'Star of the Microcosm', symbolized Man within
   the microcosm, representing in analogy the Macrocosmic universe.

       The upright pentagram bears some resemblance to the
   shape of man with his legs and arms outstretched; indeed an
   illustration attributed to Agrippa or to Tycho Brae (1582)
   illustrates the similarity of proportion in this image, showing
   the five planets and the moon at the center point - the genitalia.
   There are other illustrations of the period by Robert Fludd and
   Leonardo da Vinci showing geometrical relationships of man to the
   universe.

       Later, the pentagram came to be symbolic of the relationship
        of the head to the four limbs and hence of the pure
        concentrated essence of anything (or the spirit) to the four
        traditional elements of matter. - [Quintessence]

 In Freemasonry, Man as Microprosopus was associated with the
   five-pointed Seal of Solomon. The symbol was used, interlaced and
   upright for the sitting Master of the Lodge. The geometric
   properties and structure of the Endless Knot were appreciated and
   symbolically incorporated into the 72 degree angle of the
   compasses. 
  The women's branch of freemasonry uses the five pointed 'Eastern
   Star' as its emblem. Each point commemorates a heroine of biblical
   lore.

       No graphical illustration of any association of the pentagram
        with evil appears until the nineteenth century. Eliphas Levi
        illustrates the upright pentagram of microcosmic man beside
        an inverted pentagram with the goat's head of Baphomet.

   In ritual magick the sign has long been used as a ritual flourish
   of the athame to symbolize invoking or banishing in respect to
   elemental associations.

  In the 1940's Gerald Gardner adopted the pentagram with two points
   upward as the sigil of second degree initiation in the newly
   emergent, neo-pagan rituals of witchcraft, later to become known
   as Wicca. The one-point upward pentagram together with the upright
   triangle symbolized third degree initiation.
 The pentagram was also inscribed on the altar pentacle, it's
   points symbolizing the three aspects of the Goddess plus the two
   aspects of the God.
 * It was not until the late 1960's that the pentagram again became
   an amuletic symbol to be worn and has since then become firmly
   established as a common neo-pagan and Wiccan symbol, acquiring
   many aspects of mystique and associations that are today often
   considered to be ancient folk-lore!

Nevertheless, the potency of a symbol has more to do with its associations and its commonality than with its antiquity and the pentagram today is ubiquitous amongst neo-pagans.

A pentagram (sometimes known as a pentalpha or pentangle or, more formally, as a star pentagon) is the shape of a five-pointed star drawn with five straight strokes. The word pentagram comes from the Greek word πεντάγραμμον (pentagrammon), a noun form of πεντάγραμμος (pentagrammos) or πεντέγραμμος (pentegrammos), a word meaning roughly “five-lined” or “five lines”.

Pentagrams were used symbolically in ancient Greece and Babylonia, and are used today as a symbol of faith by many Wiccans, akin to the use of the cross by Christians and the Star of David by Jews. The pentagram has magical associations, and many people who practice Neopagan faiths wear jewelry incorporating the symbol. Christians once more commonly used the pentagram to represent the five wounds of Jesus,[1][2] and it also has associations within Freemasonry.[3]

The pentagram has long been associated with the planet Venus, and the worship of the goddess Venus, or her equivalent. It is also associated with the Roman word lucifer, which was a term used for Venus as the Morning Star, associated with the bringer of light and knowledge. It is most likely to have originated from the observations of prehistoric astronomers.[4] When viewed from Earth, successive inferior conjunctions of Venus plot a nearly perfect pentagram shape around the zodiac every eight years.[5]

The word “pentacle” is sometimes used synonymously with “pentagram”, although their technical usages are different, and their etymologies may be unrelated.[6] Wiccans and Neo-pagans often refer to a pentagram enclosed in a circle as a ‘pentacle’.[7]
