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.
If the point is directed downwards, it will represent the sexual nature of the female, water, and religions connected to goddesses. The triangle is called a blade when it points upwards. The upward triangle can represent ambition and rising up. It will symbolize the force of the male and fire. The triangle that points upward has a phallic origin.
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 heavens 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.
