U+221F "∟" Right Angle Unicode Character
Unicode Version 17.0
∟
U+221F "∟" Right Angle is a typographic symbol that represents a 90 degree angle, commonly used in geometry, mathematics, and technical drawing to denote perpendicularity or a right angle in diagrams and formulas. It is distinct from the similar looking corner bracket or square shape and is encoded in the Mathematical Operators block of Unicode, allowing it to be displayed consistently across digital platforms and fonts. Its compact design makes it useful for notation in educational materials, engineering schematics, and scientific publications where precise angular relationships must be communicated.
