A hexagram is a six-pointed star formed by the overlapping of two equilateral triangles. This geometric shape is often associated with various cultural and spiritual meanings, including its use in Judaism as the Star of David. The hexagram can also be found in Hinduism and Buddhism, where it symbolizes the union of opposites. In mathematics, a hexagram can be represented as a regular hexagon with lines connecting non-adjacent vertices. It is also used in alchemy and esoteric traditions to represent the balance of elements. The hexagram's symmetrical design makes it a popular motif in art and architecture across different cultures.
