About the identical to symbol

Represented by three horizontal bars, this mathematical operator is officially known as Identical To. In spoken language and academic contexts, it is most frequently read aloud as "is identical to" or "is congruent to." While it belongs to the common script, it remains a specialized character used primarily to denote a stronger relationship than a standard equals sign.

This symbol appears most often in professional mathematics, logic, and physics. It is commonly used to designate geometric congruence between two shapes, modular arithmetic relationships, or a definition where two expressions are identical by nature rather than just value. Outside of pure mathematics, it is occasionally employed in computer programming or logic notation to represent a triple-equals comparison for strict equality.
