Triangles are just about everywhere, from dollar bills to car dashboards. While many triangular symbols are linked to religious beliefs (like the Holy Trinity), there’s lots more to these sharp shapes than what meets the eye. In this article, we’ll break down exactly what all these different triangles represent, including alchemic and spiritual symbols.

Things You Should Know

The triangle symbol is often associated with Christianity and the 3 parts of the Holy Trinity: God the Father, Jesus Christ the Son, and the Holy Spirit.
The alchemic elements of fire, water, air, and earth are depicted with variations of upright and upside-down triangles.
The Eye of Providence (an eye in the middle of a triangle) was used as a religious symbol for God in the Renaissance period. It’s commonly seen on the US dollar bill.

Equilateral triangle In math, an equilateral triangle is a triangle where all 3 angles are exactly 60 degrees. This shape is thought by some to represent perfection, and some Christians even treat the triangle as a symbol of God and the Holy Trinity.^{[1]

- A father, mother, and child
- The past, the present, and the future
- The mind, body, and spirit
- The beginning, middle, and end
- Birth, life, and death
Inverted triangles are thought to symbolize womanhood, motherhood, and the moon. This contrasts directly with upright triangles, which represent the sun and masculinity.
