What is the significance of the elemental triangle symbols in alchemy and how do they relate to the practice of transmutation?

The elemental triangle symbols in alchemy represent the four classical elements: earth, air, fire, and water. These elements are believed to be the building blocks of all matter. In alchemy, transmutation is the process of transforming one element into another, and the elemental triangle symbols are used to understand and manipulate this process. Each element has its own properties and associations, and alchemists use these symbols to guide their experiments and rituals in pursuit of transmutation.
