Equals signs, also known as equal signs or equality symbols, are mathematical symbols used to signify that two values are equal to each other. There are several synonyms for equals signs, including equivalence signs, congruence signs, and identity signs. Equivalence signs are often used in algebraic equations and represent the concept of equivalence between two expressions. Congruence signs, on the other hand, are used in geometry to indicate that two shapes have the same size and shape. Identity signs represent the concept of an equation being true for all values of the variables involved. All these synonyms are commonly used in mathematics to denote the concept of equality.
