Characters to distinguish
- ∟ — Right Angle Symbol

Meaning and usage
Represents a square shape, an empty box, or an end-of-proof marker in some contexts.
Use it only when the surrounding notation makes the intended geometric or logical meaning clear.
Pronunciation: white square
Formula examples
\square ABCDHow to type White Square
- Windows
- Use Character Map and search for White Square, or paste the Unicode character (U+25A1).
- macOS
- Open Character Viewer with Control–Command–Space and search for White Square.
- Microsoft Word
- In an equation, type \square and press Space when Word supports the command; otherwise insert the Unicode character.
- 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 \square.
- Excel
- Paste □ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Define the logical convention before using □; proof, programming, and Boolean-algebra sources may assign different precedence or direction.
- For plain text, copy □ as U+25A1; for structured equations, use \square in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is White Square.
When to use □
- Use □ in plain text when a Unicode character is appropriate and the destination preserves U+25A1.
- Use \square in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when White Square is used in geometry, logic with a field-specific convention.
Look-alikes and related characters
