# Both reflexive and relationship

### Reflexive relation - Wikipedia

In mathematics, a binary relation R over a set X is reflexive if every element of X is related to The equality relation is the only example of a both reflexive and coreflexive relation, and any coreflexive relation is a subset of the identity relation . Then in this list of pairs, we select those which satisfy the relation R. For example, for .. by xRy ↔ x = y, then this relation is reflexive, because it is true that x is. If R, S are both reflexive, then R∩S is reflexive. Proof: Suppose a∈A. Since R, S are both reflexive on A, (a, a) ∈R and (a, . Let R be a relation on a set A. T.
