👉 An isorithm (also known as an equivalence relation) is a binary relation that is reflexive, symmetric, and transitive. This means that if a ∈ A and b ∈ B, then a = b. The symbol used to denote this type of relation is ≡. For example, consider the following two relations: 1. \(R_1\) on set A: \(a \sim b\) if and only if \(b = a + 2\) -
