U+299B "⦛" Measured Angle Opening Left Unicode Character
Unicode Version 17.0
⦛
U+299B "⦛" Measured Angle Opening Left is a typographic symbol that represents a measured angle oriented to the left, often used in technical notation, geometry, or engineering to indicate a specific angular opening. It belongs to the block of Miscellaneous Mathematical Symbols B, designed for precise representation in mathematical and scientific documents. Its glyph typically shows an angle with a small horizontal bar or mark near the vertex, signifying that the angle's measure is known or quantified, rather than arbitrary. This character helps avoid ambiguity in diagrams or equations where standard angle symbols might need directional clarification.
