The ⊾ (Right Angle With Arc) symbol is a mathematical operator used in geometry to represent an angle measuring exactly 90 degrees. While standard right angles are typically denoted with a small square, this variation includes a curved arc to maintain visual consistency with other arc-measured acute or obtuse angles in the same diagram. It is primarily used in mathematical textbooks, CAD software, and academic documentation.
