It is based upon properties of relations. *Explanation is mandatory. Check whether the following relations are reflexive, symmetric, transitive and anti-symmetric and hence verify that is the relation an equivalence relation. 1) The relation R={(1,2),(2,1),(3,2),(2,3)} on set A={1,2,3}. 2)The relation R={(1,2),(2,3),(1,3)} on set A={1,2,3}. 3)The relation R={(1,1),(2,2),(3,3),(1,2),(2,1),(2,3),(3,2),(1,3),(3,1)} on set A={1,2,3}
