Prove reflexive symmetric transitive

WebbReflexive relation. In mathematics, a binary relation R on a set X is reflexive if it relates every element of X to itself. [1] [2] 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 ... Webb2 aug. 2024 · Reflexivity, transitivity, and symmetry are three distinct properties that represent equivalent relations. A reflexive relation in relation and function is where each element maps with itself. For instance, if set A = {1,2} thus, the reflexive relation R = { (1,1), (2,2) , (1,2) , (2,1)}. Therefore, the relation is reflexive when :
