U+223D "∽" Reversed Tilde Unicode Character

U+223D "∽" Reversed Tilde is a mathematical symbol that resembles a tilde flipped horizontally, often used in geometry and logic to denote similarity or equivalence, particularly indicating that two figures are similar in shape but not necessarily in size, as an alternative to the standard tilde operator. It also appears in some contexts of formal language theory and vector notation, where it can represent a range of relations such as proportionality or approximation, complementing its mirrored counterpart in typesetting and mathematical expression.
