U+29A0 "⦠" Spherical Angle Opening Left Unicode Character
Unicode Version 17.0
⦠
U+29A0 "⦠" Spherical Angle Opening Left is a mathematical symbol used in geometry and technical notation to represent a spherical angle that opens to the left, often indicating a three-dimensional angular measurement on the surface of a sphere rather than a planar angle. It belongs to the Miscellaneous Mathematical Symbols-B block, where it serves as a distinct typographic alternative to similar angle symbols, enabling precise communication in fields like crystallography, physics, and advanced geometry. The glyph typically resembles an angle bracket that is rotated or skewed to emphasize its spherical context, distinguishing it from standard angle symbols like ∠ or ∡.
