But in fact, not everything is so simple, because the Triangle is a universal geometric figure, whose symbolic interpretation is determined by the type, location or combination of triangles.
An equilateral triangle with an upward pointing apex personifies divine perfection and harmony, serves as a sign of the sun and fire, life and heart, mountains and spiritual uplift. The upside down triangle is the sign of the moon, water and rain. Two such triangles, touching at the tops, symbolize cyclicity, the waxing and waning moon, the beginning and the end, life and death. At the point of their contact, a radical transformation takes place, one phenomenon turns into the opposite. Finally, two intersecting equilateral triangles forming a hexagram (a six-pointed star, called in occultism the "Shield of David" or "Seal of Solomon"), signify the unity of opposites.
The symbolism of an equilateral triangle is closely connected with man. The triangle with its apex pointing upwards is an ancient phallic sign, a symbol of creative male power; an inverted triangle is an even more ancient sign of the feminine, a symbol of fertility and the emblem of the mother goddess. "Female" and "male" triangles, connected by vertices, naturally constitute the emblem of sexual harmony.
In the philosophy of the Pythagoreans, a geometric figure with three angles was a symbol of the number "3" and an emblem of wisdom, rightfully belonging to the goddess Athena.
In the religion of the Egyptians, Hindus, Celts, Scandinavians, Aztecs, Incas and many other peoples, the triangle could personify the triad of the main gods. The Egyptians, for example, associated the vertical side of the triangle with Osiris, the horizontal side with Isis, and the hypotenuse with their son Horus.
In Christian iconography, the three hypostases of God (God the Father, God the Son and the Holy Spirit) that make up the Holy Trinity were depicted either in the form of an equilateral triangle or in the form of a triangle formed by three intersecting circles. The symbols of the triune Christian God were also a triangular halo and an eye in a triangle (the emblem of the "God's eye").
