U+22BE "⊾" Right Angle with Arc Unicode Character

U+22BE "⊾" Right Angle with Arc is a geometric symbol that visually represents a right angle, typically denoted by the standard perpendicular corner, but distinguished by having a small curved arc drawn between its two arms instead of a square or dot. This symbol is used in mathematical notation, especially in geometry, to indicate a ninety degree angle while the arc clarifies the specific angular measurement in degrees, often appearing in diagrams or proofs alongside other angle markers. Its unique design helps avoid ambiguity in complex figures where multiple angles or right angle indicators may be present.
