How does the triangle represent divine wisdom in Masonic teachings?

When rays emanate from its center—a form known as the radiated triangle—it symbolizes the Divine Light, representing the Eternal Light of Wisdom that surrounds the Supreme Architect and emanates throughout creation, as Albert C. Mackey explains 1.

In its basic form, the triangle or delta serves as an emblem of Deity, representing active force and divine nature, in contrast to the square, which typifies passive matter and humanity 1. Where two triangles interlace, Mackey writes that the balance of light and dark represents the opposing forces present in human life, including the continual interplay between ignorance and wisdom 1.
