Homothetic Symbol
The ∻ symbol represents a homothety—an affine transformation involving scaling and translation.
U+223B
∻ is the Unicode homothetic symbol (U+223B). It’s commonly used in mathematics notation to indicate a homothety or related geometric mapping. Below you’ll find practical ways to copy and use it in text, design, and code.
Homothetic Symbol Meaning
The symbol ∻ (Unicode name: HOMOTHETIC, U+223B) is used in mathematical contexts to denote a homothety, which is a transformation that scales figures while keeping the lines through corresponding points aligned. In geometry, it often appears when describing mappings between similar figures, such as circles, polygons, or other shapes under uniform dilation plus translation. Depending on the source, ∻ may be read as “homothetic to” or as a marker for a homothetic relationship between two objects. If you’re typesetting geometry or writing about transformations, this symbol helps communicate the intended geometric mapping clearly.
Common uses
- •Labeling homothetic transformations in geometry notes and textbooks
- •Indicating similarity-related relationships between shapes in diagrams
- •Annotating scale-and-translate mappings in educational worksheets
- •Writing math content for blogs, presentations, and study materials
- •Using as a specialized operator in technical documents and drafts
