In mathematics, a binary relation R over a set X is reflexive if every element of X is related to itself. Formally, this may be written∀x ∈ X : x R x.
An example of a reflexive relation is the relation "is equal to" on the set of real numbers, since every real number is equal to itself. A reflexive relation is said to have the reflexive property or is said to possess reflexivity. Along with symmetry and transitivity, reflexivity is one of three properties defining equivalence relations.
