What You'll Learn

How to display the angle symbol (∠, U+2220) in HTML. Unicode calls this character ANGLE; it is the usual geometric “angle at a point” mark (for example in expressions like ∠ABC). It lives in the Mathematical Operators block.

You can write it as the named entity &​ang; (omit the zero-width space when typing: ampersand + ang + semicolon), as &#x2220; or &#8736;, or via CSS content with \2220 or \022220. Do not confuse it with angle brackets (<, >) or quotation ornaments; those are different code points.

Complete HTML Example

This example shows U+2220 using hexadecimal, decimal, the named ang entity, and a CSS content escape. In your own file, write the named form without the zero-width space used in this table.

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point:after{
   content: "\2220";
  }
 </style>
</head>
<body>

<p>Angle using Hexa Decimal: &#x2220;</p>
<p>Angle using HTML Code: &#8736;</p>
<p>Angle using HTML Entity: &​ang;</p>
<p id="point">Angle using CSS Entity: </p>

🌐 Browser Support

Named and numeric references for U+2220 work in all modern browsers. The glyph depends on fonts that include Mathematical Operators:

Chrome 1+
Firefox 1+
Safari 1+
Edge 12+
Opera 4+
Android 4.4+
iOS Safari 1+

👀 Live Preview

See U+2220 in short math-style strings (font-dependent):

Isolated glyph ∠
With points ∠ABC = 90°
Numeric refs Same character as &#x2220; or &#8736; in UTF-8 text.
Monospace U+2220 ANGLE
Font note STIX, Cambria Math, or other math-capable stacks improve consistency with textbook notation.

🧠 How It Works

1

Named entity

The short name ang (with leading ampersand and semicolon) resolves to U+2220. It is easy to read in hand-authored math HTML.

HTML markup
2

Numeric references

&#8736; (decimal) and &#x2220; (hex) are equivalent for the angle symbol.

HTML markup
3

CSS escape

\2220 (or \022220 with a following space if the next character is hex) in content on ::before / ::after emits U+2220 from a stylesheet.

Same code point

All paths expose U+2220 (Mathematical Operators). Official name: ANGLE. Prefer named or numeric references in markup; use CSS escapes only in stylesheets.

✅

Use Cases

The angle symbol (U+2220) fits these kinds of content:

📐 Geometry & trig

Angle labels in proofs, exercises, and static diagrams alongside plain text.

🎓 Teaching sites

K–12 and university pages that introduce notation without full MathML.

🔬 Technical docs

Engineering and CAD copy where a single Unicode glyph is enough.

📈 Diagram captions

SVG or figure captions that name angles next to illustrations.

💻 Calculators & apps

UI strings for geometry tools and graphing helpers.

♿ Accessibility

Pair symbols with readable text (“angle ABC”) so meaning survives font fallback.

📚 Unicode tables

Reference pages for Mathematical Operators.

💡 Best Practices

Do

  • Prefer the named ang entity (ampersand + ang + semicolon, no separator) or numeric refs for portable math snippets
  • Use a math-friendly font stack when notation must match textbooks
  • Keep labels like ∠ABC near the figure they describe
  • Use \2220 only inside CSS content, not raw in HTML text
  • Validate pages; bad nesting around math can still confuse assistive tech

Don’t

  • Confuse U+2220 with less-than, greater-than, or bracket ornaments
  • Rely on a casual body font if the angle glyph must match examination-board charts
  • Paste CSS escapes into HTML markup (wrong layer)
  • Use images for every tiny symbol when HTML entities would stay crisp and selectable
  • Forget context for screen readers when the symbol carries the whole meaning

Not the same as angle brackets; pick the right code point for markup vs math

❓ Frequently Asked Questions

Use the named ang reference (ampersand + ang + semicolon), &#8736;, or &#x2220; in text. For CSS-only generated text, \2220 in content works.
U+2220 (decimal 8736, hex 2220). Official name: ANGLE. Block: Mathematical Operators.
No. Angle brackets for markup use < and > (different code points). U+2220 is the mathematical angle glyph.
Markup uses named or numeric references in the document. CSS uses backslash hex escapes inside content and other property values.
Yes: the standard short name is ang with the usual leading ampersand and trailing semicolon.
