Reflexive Relation - Definition, Formula, Examples

WebA relation \(R\) on a set \(A\) is an equivalence relation if it is reflexive, symmetric, and transitive. If \(R\) is an equivalence relation on the set \(A\), its equivalence classes form a partition of \(A\). In each equivalence class, all the elements are related and every element in \(A\) belongs to one and only one equivalence class.
