\2220
The ∠ symbol represents a geometric angle, commonly used in mathematical notation to denote the space formed by two intersecting lines or surfaces. Included in Unicode's Mathematical Operators block, it is explicitly designed for equations and blueprints to distinguish it from the standard less-than sign (<). Beyond geometry textbooks, you will often see it in electrical engineering and physics discussions to express phase angles and trajectories.

How to Type

Windows
Alt+8736 or Win+. then search "angle"
macOS
Control+Command+Space then search "angle"
Linux
Ctrl+Shift+U then 2220
HTML
&ang; or &#x2220;

In Programming

In technical documentation and markup languages like LaTeX, the angle symbol is rendered using the `\angle` command. It is also frequently utilized in electrical engineering software to parse or display phasor notation, representing magnitude and phase (e.g., 120∠45°).
