The triangle as a symbol is connected to the number three for obvious reasons. It can represent different things if it is oriented in different directions. It can symbolize gender based on how it is positioned. It will symbolize the power of the male, fire, and a false view of God when the point is directed upwards. Christians will see the triangle as a symbol of the Trinity.
The triangle is called a chalice when it points downward. The triangle will represent water because in that position it flows downward. It can symbolize heaven’s grace and the womb. The triangle that points downward is one of the oldest symbols of the divine power of the female. It is an ancient symbol that represents the genitalia of a goddess.
The nine points of the triangle have been associated with the nine worlds of Norse mythology, and the three interconnected triangles have been said to reflect the connection between Earth, Heaven and Hell. The symbol has also been associated with ecstatic Seidr magic, of which Odin was a master.
