An "angle bracket" is a type of punctuation mark that resembles a pointed symbol, typically used in pairs. The most common forms are the less-than sign (<) and the greater-than sign (>). These symbols are often used in mathematics, programming, and markup languages like HTML to denote relationships or to enclose elements. In computing, angle brackets are frequently used to define tags in XML and HTML, helping to structure content on the web. They can also indicate generic types in programming languages like C++ and Java, allowing developers to create flexible and reusable code components.
