U+2261 "≡" Identical To Unicode Character

U+2261 "≡" Identical To is a mathematical symbol that denotes a relationship of absolute equivalence or congruence between two expressions, indicating that they are exactly the same in value, form, or meaning under all circumstances. It is commonly used in various fields such as geometry to signify congruent figures, in modular arithmetic to express equivalence modulo a number, and in logic to represent strict identity rather than mere equality. Unlike the standard equals sign, which can sometimes imply conditional equality, the triple bar asserts a stronger, invariable sameness.
