Question

A relation R in = {1,2,3} is defined as = {(1, 1), (1, 2), (2, 2), (3, 3)}. prove it reflexive and transitive​

Answer 1

So, R is reflexive. (1, 2) and (2, 3) are elements of R. R would be a symmetric relation if (2, 1) and (3, 2) would be the elements of R. Since, (2, 1) and (3, 2) are not the elements of R so, R is not symmetric.
