When is a relation R on a set A not symmetric ?
Let X= {1,2,3,4} and R be a relation on set X defined by R ={(1,2), (3,4), (2,2), (4,3), (2,3) }. Is R symmetric on X?

A relation R on a set A is not symmetric if there are two distinct elements a ,b `in` A such that (a,b) `in R and (b,a) `in` R or (b,a) `in` R and (a,b) `in` R No.
