Not parallel to (∦) is the Mathematical Operators character at Unicode U+2226 (NOT PARALLEL TO). In geometry, AB ∦ CD means line AB is not parallel to line CD. HTML5 provides ∦, ∦, and &NotParallel;.
Remember
Character ∦
Unicode U+2226
Named entity ∦ (also ∦, &NotParallel;)
Hex entity ∦
Decimal ∦
CSS escape \2226
All of these produce the same glyph: ∦. Prefer ∦ for readable HTML; paste ∦ in UTF-8 when convenient.

How It Works
1. Named:∦ (or ∦) is the clearest HTML form for U+2226.
2. Hex:U+2226 → ∦ in HTML. Reliable numeric form.
3. Decimal: same code point as 8742 → ∦. Same glyph.
4. Direct: paste ∦ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \2226 in content (not an HTML entity). #point::after appends that ∦ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with this geometry entity.
Opposite
∦ vs ∥
∥ means parallel. ∦ means not parallel. Use the correct polarity for your statement.
Not ≠
Not a generic inequality
≠ means not equal. Parallelism is a different relation — prefer ∦ in geometry.
Aliases
∦ = ∦
Both (plus &NotParallel;) map to U+2226. Pick one and stay consistent.
CSS vs HTML
Do not mix escapes
\2226 belongs in CSS. ∦ / ∦ / ∦ belong in HTML.
Semicolon
End references
Always finish with ; — write ∦, not &npar.
UTF-8
Declare charset
If you paste ∦ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
Compatibility
Browser Support
Not parallel to (U+2226) and its entity forms (∦, ∦, ∦, CSS \\2226) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
Not Parallel To (∦)
Prefer ∦, or encode with hex, decimal, or CSS escape — same glyph everywhere.

Bottom line: Prefer ∦ (or ∦) in HTML. Use ∦ / ∦ when a numeric form is required, and \\2226 only inside CSS content.
Remember
Key Takeaways
Unicode: not parallel to is U+2226 (decimal 8742), Mathematical Operators.
HTML: prefer ∦ (aliases ∦, &NotParallel;), or ∦ / ∦.
CSS: use \2226 inside content for generated text.
Meaning: not parallel — opposite of ∥, not the same as ≠.
Use ∦ or ∦ (named), ∦ (hex), ∦ (decimal), type ∦ in UTF-8, or the CSS escape \2226 in content. All render ∦.
U+2226 (NOT PARALLEL TO). Hex 2226, decimal 8742. It belongs to Mathematical Operators and means two lines (or vectors) are not parallel.
Yes. HTML5 defines ∦, ∦, and &NotParallel; (aliases for the same character). You can also use ∦ or ∦.
Use it in geometry and math when writing AB ∦ CD (line AB is not parallel to line CD). Prefer ∦ for readable source. For ordinary English, write “is not parallel to” in words.
HTML entities (∦, ∦, or ∦) go in markup. The CSS escape \2226 is used in stylesheets (usually in the content property of ::before/::after). Both render ∦.
∥ (U+2225, ∥) means parallel. ≠ (U+2260, ≠) means not equal. ∦ specifically means not parallel — do not substitute a generic inequality.
🤔
Did you know?
Not parallel to (∦) is Unicode U+2226 (decimal 8742) — NOT PARALLEL TO in Mathematical Operators. HTML5 provides ∦ (also ∦ and &NotParallel;). It negates parallel ∥ (U+2225, ∥).
