The Mathematical Symbol "Right-Pointing Angle Bracket (⟩)"
The "Right-Pointing Angle Bracket" Symbol (⟩)
The ⟩ symbol, often referred to as the "Right-Pointing Angle Bracket" or simply "Closing Angle Bracket," is commonly used in a variety of contexts in mathematics, computing, and linguistics.
Mathematical Usage
In mathematics, the ⟩ and its counterpart ⟨ (Left-Pointing Angle Bracket) are used to denote inner products or scalar products in linear algebra, especially in the context of vector spaces.
Example:
If \( \vec{a} \) and \( \vec{b} \) are vectors, their inner product can be represented as \( ⟨ \vec{a}, \vec{b} ⟩ \).
Computing and Programming
In computing, the ⟩ symbol, along with its counterpart ⟨, is widely used in various programming languages and data formats to denote specific elements or to structure data:
- HTML/XML: The ⟩ is used as the closing part of a tag. For example:
<tagname>content</tagname>. - Generics: In some programming languages, these brackets are used to define generic data types.
Linguistics
In the field of linguistics, angle brackets are used to enclose a sequence of characters, indicating that the sequence represents phonetic or phonemic data.
Conclusion
The ⟩ symbol, though simple, has diverse applications and is integral to many mathematical expressions, programming paradigms, and linguistic annotations. Recognizing its context of use is key to understanding its intended meaning.

Codes for the 〉 Symbol
| The Symbol | 〉 | |
| Alt Code | Alt 9002 | |
| HTML Code | 〉 | |
| HTML Entity | ⟩ | |
| CSS Code | \232A | |
| Hex Code | 〉 | |
| Unicode | U+232A |
How To Insert the 〉 Symbol
(Method 1) Copy and paste the symbol.
The easiest way to get the 〉 symbol is to copy and paste it into your document.Bear in mind that this is a UTF-8 encoded character. It must be encoded as UTF-8 at all stages (copying, replacing, editing, pasting), otherwise it will render as random characters or the dreaded �.
(Method 2) Use the "Alt Code."
If you have a keyboard with a numeric pad, you can use this method. Simply hold down the Alt key and type 9002. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)(Method 3) Use the HTML Decimal Code (for webpages).
| HTML Text | Output |
|---|---|
| <b>My symbol: 〉</b> | My symbol: 〉 |
(Method 4) Use the HTML Entity Code (for webpages).
| HTML Text | Output |
|---|---|
| <b>My symbol: ⟩</b> | My symbol: ⟩ |
(Method 5) Use the CSS Code (for webpages).
| CSS and HTML Text | Output |
|---|---|
|
<style> span:after { content: "\232A";} </style> <span>My symbol:</span> | My symbol: 〉 |
(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).
| HTML Text | Output |
|---|---|
| <b>My symbol: 〉</b> | My symbol: 〉 |
| JavaScript Text |
|---|
|
const x = "0x"+"E9" ctx.fillText(String.fromCodePoint(x), 5, 5); |
| Output |
〉 |
(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).
The Unicode for 〉 is U+232A. The important part is the hexadecimal number after the U+, which is used in various formats. For example, in Microsoft Office applications (e.g. Word, PowerPoint), do the following:| Type | Output |
|---|---|
| 232A [Hold down Alt] [Press x] | 〉 (The 232A turns into 〉. Note that you can omit any leading zeros.) |
| JavaScript Text | Output |
|---|---|
| let str = "\u232A" document.write("My symbol: " + str) | My symbol: 〉 |
