U+2A6D "⩭" Congruent with Dot Above Unicode Character
Unicode Version 17.0
⩭
U+2A6D "⩭" Congruent with Dot Above is a mathematical symbol that extends the concept of congruence (typically denoted by ≅) by adding a single dot positioned directly above the congruent sign. This character is used in advanced mathematical and logical notation to indicate a specific variant of congruence, often implying a relation that is structurally analogous to standard congruence but with an additional condition or property represented by the dot. It is part of the Supplemental Arrows and Supplemental Mathematical Operators block, which provides specialized operators for precise technical expression in formal proofs or theoretical mathematics.
