U+299D "⦝" Measured Right Angle with Dot Unicode Character

U+299D "⦝" Measured Right Angle with Dot is a typographical symbol classified under the Supplemental Mathematical Operators block, used primarily in technical and geometric notation to represent a right angle that has been measured or quantified, where the dot serves as a diacritical marker to distinguish it from a standard right angle symbol. This character is employed in fields like geometry, engineering, and drafting to indicate a specific right angle that has been designated with a point of reference or additional measurement context. Its design consists of a two-dimensional, right-angled corner shape with a small, centered dot placed inside the angle, ensuring clarity in diagrams and mathematical expressions.
