State the reason for the relation R on the set {1, 2, 3} given by R = {(1, 2), (2, 1)} not to be transitive.

Given set {1,2,3} and relation R = {(1, 2), (2, 1)}.


For relation R to be transitive:


R={(1,2),(2,3),(1,3)}


But in the given relation:


(2,3) and (1,3) R


Hence, Given Relation R is not transitive.
