Measured Angle Symbol
∡ is the symbol for a measured angle, often used to distinguish it from an angle specification.
U+2221
The symbol ∡ (U+2221) is called the measured angle. It’s commonly used in math text to indicate an angle value or reading. Use it in notes, equations, or typography where “measured” is important.
Measured Angle Symbol Meaning
∡ is the Unicode symbol named “MEASURED ANGLE” (U+2221). In mathematical writing, it typically signals that an angle is being treated as a measured quantity—such as a specific angle magnitude obtained from a measurement—rather than just a general or variable angle expression. Designers and writers also use it to visually clarify that a numeric or determined angle value is intended. Because it’s a dedicated Unicode character, it can be copied directly into documents, and it can also be inserted via HTML, CSS, or JavaScript using its provided escapes.
Common uses
- •Labeling angle measurements in geometry notes
- •Typing math proofs where a measured value must be distinct
- •Annotating diagrams in text-based documentation
- •Designing educational content or worksheets
- •Styling engineering or technical UI text that references angle readings
