Reversed Tilde Symbol
∽ is the reversed tilde symbol (U+223D) used in math notation and formatting where a “similarity-like” mark is needed.
U+223D
The symbol ∽ is called the reversed tilde. It has a specific Unicode identity (U+223D), which makes it reliable for digital design and math text. This page helps you copy it and use it in common code contexts.
Reversed Tilde Symbol Meaning
∽ (Unicode U+223D, “REVERSED TILDE”) is primarily used as a mathematical symbol. In many mathematical contexts, it conveys a relation that is closely related to “similarity” or “correspondence,” often expressed alongside other relation symbols. Because it has its own Unicode code point, it should be preferred over approximating with normal punctuation like ~ or a flipped tilde character. Outside strict math typesetting, designers sometimes use ∽ as a typographic ornament to suggest contrast, mirroring, or a reversible relation in headings, UI labels, or text-based diagrams.
Common uses
- •Mathematical writing to denote a specific relation using the reversed tilde character.
- •Typing notes, comments, or proofs where a correct symbol is important for clarity.
- •Designing typographic UI elements or labels that use relation-like symbols.
- •Creating diagram annotations or text-based schematics in math and science materials.
- •Providing accessible, copyable symbol references in documents and web content.
Examples
∽ Reversed Tilde Symbol (U+223D)
- ∽We write A ∽ B to indicate a related equivalence condition.
- ∽The transformation maps shapes so that they satisfy ∽.
- ∽For the proof, assume ∽ holds between the two structures.
- ∽In this diagram, ∽ marks the corresponding components.
- ∽Use the reversed tilde ∽ instead of a plain ~ for accuracy.
