Right Angle is a formal mathematical operator or relation symbol used in academic and technical writing — algebra, calculus, logic, or set theory — to express a precise mathematical relationship concisely.
Unicode block: Mathematical Operators (U+2200–U+22FF). This large block standardizes the symbols used across algebra, calculus, logic, and set theory, replacing the inconsistent, often hand-drawn notation used before digital typesetting.
At Unicode code point U+221F (decimal 8735), Right Angle is the 32nd of 256 characters cataloged in this category on How To Type Any Symbol. In terms of typing methods, it has a documented Windows Alt code, though no dedicated single-key Mac shortcut — Mac users generally rely on copy-paste for it. Regardless of platform, clicking the copy button above places the exact character on your clipboard, ready to paste into any application that accepts Unicode text.
💡 Good to know: In LaTeX, nearly every math operator has a dedicated command (e.g. \sum, \int, \forall) which is the standard, more reliable way to include it in technical documents rather than copy-paste.
