Meaning and usage
Marks an arc or curved relation over geometric points.
Pair it with endpoint labels or use structured LaTeX accents for complete arc notation.

Formula examples
⌒ABHow to type Arc Symbol
- Windows
- Use Character Map or enter U+2312 in a Unicode-aware application.
- macOS
- Open Character Viewer with Control–Command–Space and search by the symbol name.
- Microsoft Word
- In an equation, type \frown and press Space when Word supports the command.
- iPhone and iPad
- Copy and paste ⌒, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ⌒, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ⌒ or use Insert → Special characters. For structured math, use the equation editor and verify \frown.
- Excel
- Paste ⌒ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Preserve the orientation and decoration of ⌒; in geometry a rotated, barred, or marked symbol can represent a different relation or object.
- For plain text, copy ⌒ as U+2312; for structured equations, use \frown in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Arc Symbol.
When to use ⌒
- Use ⌒ in plain text when a Unicode character is appropriate and the destination preserves U+2312.
- Use \frown in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Arc Symbol is used in geometry, trigonometry with a field-specific convention.

Font and compatibility notes
Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.
