The ∢ (Spherical Angle) symbol is a mathematical operator used to represent an angle formed by the intersection of two great circles on the surface of a sphere. In the Unicode standard, it sits alongside other geometric symbols to help typeset complex equations. While you won't see it much on social media, it is essential for mathematicians, astronomers, and navigators working with spherical geometry.
