View source for Equivalence relation

In [[mathematics]], an '''equivalence relation''' is a [[binary relation]] that is at the same time a [[reflexive relation]], a [[symmetric relation]], and a [[transitive relation]].

As a consequence of these properties an equivalence relation provides a [[partition of a set]] into [[Equivalence class|equivalence classes]].
