Delta equal to (≜) is the Unicode character at U+225C in the Mathematical Operators block. Official name: DELTA EQUAL TO. It often means equal by definition (a triangle / delta over an equals sign).
Remember
Character ≜
Unicode U+225C
Named entity ≜
Hex entity ≜
Decimal ≜
CSS escape \225C
Not the same = · ≈ · ≡
Prefer ≜ in HTML markup (named for “triangle equal”). You can also type ≜ in UTF-8, or use numeric forms when needed.
Delta equal using Named Entity: ≜
Delta equal using Hex Code: ≜
Delta equal using HTML Code: ≜
Delta equal using CSS Entity: ≜
Typed directly: ≜
Definition: n ≜ 10
How It Works
1. Named:≜ is the HTML5 name for U+225C → ≜. Best default in markup.
2. Hex:U+225C → ≜ in HTML. Same glyph as the named form.
3. Decimal: same code point as 8796 → ≜. Same result as hex and named.
4. CSS: use \225C in content (not an HTML entity). #point::after appends that ≜ after the paragraph text.
5. Typed / definition: paste ≜ in UTF-8, or write <em>n</em> ≜ 10 for a definitional equality example.
Pitfalls & Tips
Common mistakes when working with Delta Equal To.
Name
Remember ≜
There is no &deltaequal;. The HTML5 name is ≜ (triangle equal).
=
Not plain equals
Use = for ordinary equality. Use ≜ when you mean equal by definition.
≈
Not approximately equal
≈ (≈) means approximately equal. Different operator from U+225C.
CSS vs HTML
Do not mix escapes
\225C belongs in CSS strings. ≜ / ≜ / ≜ belong in HTML.
Fonts
Math font coverage
Some fonts omit U+225C. Prefer a font with Mathematical Operators coverage for display.
Semicolon
End references
Always finish with ; — write ≜, not &trie.
Compatibility
Browser Support
Delta equal to (U+225C) and its entity forms (≜, ≜, ≜, CSS \\225C) are supported in all mainstream browsers. Visible glyphs depend on math font coverage.
✓ Universal support
Delta Equal To (≜)
Encode with named, hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

Bottom line: Prefer ≜ in HTML. Use ≜ or ≜ when numeric form is required, and \\225C only inside CSS content.
Remember
Key Takeaways
Unicode: delta equal to is U+225C (decimal 8796) — glyph ≜.
HTML: prefer ≜, or use ≜ / ≜ / type ≜.
CSS: use \225C inside content for generated text.
Meaning:≜ ≈ equal by definition — not the same as = or ≈.
One line:U+225C → ≜ / ≜ / ≜ / CSS \225C / type ≜.
Frequently Asked Questions
Use ≜ (named), ≜ (hex), ≜ (decimal), type ≜ directly in UTF-8, or the CSS escape \225C in content. Prefer ≜ in normal HTML.
U+225C (DELTA EQUAL TO). Hex 225C, decimal 8796. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. Use ≜ — the preferred form in HTML markup. Numeric forms ≜ and ≜ also work.
Use it in mathematics, logic, and engineering when a quantity is defined as equal to another (definitional equality), not just numerically equal.
HTML entities (≜, ≜, or ≜) go in markup. The CSS escape \225C goes in stylesheet strings (usually content on ::before/::after).
trie is short for triangle equal — the glyph looks like a triangle (delta) over an equals sign. It is the HTML5 name for U+225C.

Did you know?
Delta equal to is Unicode U+225C (decimal 8796) — glyph ≜ in the Mathematical Operators block. HTML5 names it ≜ (triangle equal). It often means equal by definition. It is not a plain equals sign = or approximately equal ≈.
