Pentagram

A pentagram is a five-pointed star, with all lines the same length and all angles the same. A 'pentangle', 'star pentagon', or 'pentalpha' means the same thing. It is a type of pentagon.

The word pentacle originally meant 'any symbol that defies against pureness spirits'. There are many of such symbols, only a few of which include a pentagram. During the modern age of Wicca, the word 'pentacle' acquired a second definition, due to sounding similar to the word 'pentagram', and the fact that wiccan pentacles use a pentagram. That second definition of 'pentacle' is 'a circumscribed pentagram', which means 'a pentagram drawn inside a circle so that the points of the pentagram touch the circle'.

The pentagram has been portrayed as a satanic symbol in popular media.
