U+223B "∻" Homothetic Unicode Character
Unicode Version 17.0
∻
U+223B "∻" Homothetic is a mathematical symbol used in geometry and transformational theory to denote a homothety, which is a scaling transformation that expands or contracts figures around a fixed center point. Resembling a tilde with a vertical bar or a stylized proportionality sign, this character operates within the "Mathematical Operators" block and is employed in scholarly contexts to express similarity or ratio relationships between geometric shapes. Its specific encoding ensures that mathematicians and researchers can represent the concept of a homothety consistently across digital texts, distinguishing it from visually similar but functionally distinct symbols like the tilde or equivalence sign.
