Angle Symbol
The ∠ symbol represents an angle and is commonly used in math notation and diagrams.
U+2220
The ∠ symbol (angle) is a concise way to label angles in writing, diagrams, and educational content. It’s widely recognized in mathematics and geometry. You can copy it directly or use standard Unicode escapes in code.
Angle Symbol Meaning
∠ is the Unicode symbol named ANGLE (U+2220) and is used to denote an angle in geometry and math contexts. It commonly appears in expressions like “∠ABC,” where letters label the angle’s vertex and rays, or in measurements such as “∠A = 45°.” Beyond textbooks, it’s also useful in plain text when you need a clear visual cue that something refers to an angle—like describing corners, pivots, or directional changes. In typography, ∠ provides a consistent symbol for angle labeling without spelling out the word “angle” every time.
Common uses
- •Labeling angles in geometry problems (e.g., ∠ABC).
- •Writing angle measurements in notes and worksheets (e.g., ∠A = 60°).
- •Annotating diagrams in presentations or diagrams for corners and turns.
- •Using in math-themed UI text like “Find ∠x.”
- •Creating clear, compact notation in documentation or study guides.
