HTML Entity for Not Parallel To (∦)
What You'll Learn
How to display the Not Parallel To symbol (∦) in HTML using named, hexadecimal, decimal, and CSS escape methods. This geometric relation operator states that two lines or objects are not parallel (e.g. line AB ∦ line CD).
This character is U+2226 (NOT PARALLEL TO) in the Mathematical Operators block (U+2200–U+22FF). Render it with the named entity ∦, ∦, ∦, or CSS escape \2226. Compare with the parallel symbol (∥, ∥, U+2225) and Equal Parallel To (⋕, ⋕).

<style>
#point::after{
content: "\2226";
}
</style>
</head>
<body>
<p>Symbol (hex): ∦</p>
<p>Symbol (decimal): ∦</p>
<p>Symbol (named): ∦</p>

🧠 How It Works
Named Entity
∦ is the HTML named entity for U+2226—the most readable choice when writing geometry-relation markup.
Hexadecimal Code
∦ uses the Unicode hexadecimal value 2226 to display the not-parallel symbol.
Decimal HTML Code
∦ uses the decimal Unicode value 8742 to display the same character.
CSS Entity
\2226 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce: ∦. Unicode U+2226 in Mathematical Operators (U+2200–U+22FF).
Use Cases
The ∦ symbol (∦) is commonly used in:
Expressing that two lines or planes are not parallel.
Textbooks, papers, and lecture notes published as HTML.
Technical drawings and specifications in web documentation.
Computer graphics and geometry courses with web notation.
Interactive math modules with web-based notation.
Unicode charts and HTML entity documentation for math symbols.
💡 Best Practices
Do
- Use
∦for readable geometry-relation markup - Distinguish ∦ from ∥ (parallel) and ⋕ (equal and parallel)
- Pair ∦ with plain-language description on first use
- Use numeric references in generated or XML-first workflows
- Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Confuse ∦ (
∦) with ∥ (∥) - Confuse ∦ with ⊥ (
⊥, perpendicular) - Use padded Unicode notation like U+02226—the correct value is
U+2226 - Put CSS escape
\2226in HTML text nodes - Use
\02226in CSS—the correct escape is\2226
