HTML Entity for Homothetic (∻)
What You'll Learn
How to display the Homothetic (∻) symbol in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This character is U+223B (HOMOTHETIC) in the Mathematical Operators block (U+2200–U+22FF).
Render it with ∻, ∻, ∻, or CSS escape \223B. This glyph denotes homothety in geometry—a scaling transformation from a center point. It has a named HTML entity (∻) for readable markup.

🧠 How It Works
Hexadecimal Code
∻ uses the Unicode hexadecimal value 223B to display the symbol. The x prefix indicates hexadecimal format.
Decimal HTML Code
∻ uses the decimal Unicode value 8763 to display the same character.
Named Entity
∻ is the semantic named entity for ∻—readable in source HTML and part of the HTML5 character set.
CSS Entity
\223B is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce the glyph: ∻. Unicode U+223B is in Mathematical Operators. Next: Homothetic Above.
Use Cases
The Homothetic symbol (∻) is commonly used in:
Denote homothety (scaling from a center) in figures and proofs.
Geometry textbooks, course notes, and tutorials on transformations.
Express homothetic relations between shapes or sets in equations.
Geometry, topology, and applied mathematics publications on the web.
CAD, graphics, or geometry APIs that use homothety operations.
Web-based equation editors and transformation formula display.
💡 Best Practices
Do
- Use
∻for readable source markup - Use math fonts (Cambria Math, STIX, Noto Sans Math) for reliable rendering
- Keep one method (named, hex, or decimal) consistent across the document
- Add visible text (e.g. “homothetic” or “homothety”) for accessibility
- Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Put CSS escape
\223Bin HTML text nodes - Confuse ∻ with unrelated operators (e.g.
⊹, U+22B9) - Assume every system font renders Mathematical Operators clearly
- Rely on the symbol alone for screen reader users
- Skip browser testing for math-heavy pages
