U+2222 "∢" Spherical Angle Unicode Character
Unicode Version 17.0
∢
U+2222 "∢" Spherical Angle is a mathematical symbol that represents an angle formed on the surface of a sphere, typically measured in radians or degrees and often used in geometry and trigonometry when dealing with spherical triangles or solid angles. Unlike a standard planar angle, which is defined by two intersecting lines in a flat plane, the spherical angle is defined by the intersection of two great circles on a sphere, making it a key component in fields such as astronomy, cartography, and navigation for calculations involving curved surfaces.
