🧠 How It Works
Hexadecimal Code
≑ uses the Unicode hexadecimal value 2251 to display the Geometrically Equal To symbol. The x prefix indicates hexadecimal format.
Decimal HTML Code
≑ uses the decimal Unicode value 8785 to display the same character.
Named Entity
≑ is the semantic named entity for ≑—the easiest to read in source HTML and part of the HTML5 character set.
CSS Entity
\2251 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+2251 is in Mathematical Operators (U+2200–U+22FF). Next: Geometrically Equivalent To (≎).
Use Cases
The Geometrically Equal To symbol (≑) is commonly used in:
Notation involving geometric equality or equality by definition in geometry.
Textbooks, proofs, and content that express geometric equality between figures.
Papers, specifications, and documentation using mathematical operators.
Online courses, tutorials, and resources for math or geometry.
HTML entity lists, Unicode charts, and math symbol documentation.
Web pages displaying mathematical expressions with proper typography.
💡 Best Practices
Do
- Use
≑for readable source markup - Pick one style (hex / decimal / named) per project
- Use math fonts (e.g. Cambria Math) for reliable glyph rendering
- Consider MathML for complex equations and accessibility
- Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Confuse ≑ (geometrically equal) with ≎ (geometrically equivalent)
- Use ordinary
=when ≑ is the intended operator - Put CSS escape
\2251in HTML text nodes - Mix entity styles randomly in one file
- Rely on the symbol alone without context for screen readers
