U+29AA "⦪" Measured Angle with Open Arm Ending in Arrow Pointing down and Right Unicode Character
Unicode Version 17.0
⦪
U+29AA "⦪" Measured Angle with Open Arm Ending in Arrow Pointing down and Right is a specialized mathematical symbol used primarily in geometry and technical notation to denote a measured angle where one of its defining arms extends into an arrow directed downward and to the right. It belongs to the Miscellaneous Mathematical Symbols-B block and is often employed in diagrams or formulas to indicate a specific angular measurement, particularly when the orientation or direction of the angle's arm is significant for the problem or proof. This symbol combines the conventional angle notation with a directional arrow, allowing it to convey both the measure and the spatial relationship of the angle's sides in a compact visual form.
