WebSymmetric Relations Examples Example 1: Suppose R is a relation on a set A where A = {1, 2, 3} and R = { (1,1), (1,2), (1,3), (2,3), (3,1)}. Check if R is a symmetric relation. Solution: As we can see (1, 2) ∈ R. For R to be symmetric (2, 1) should be in R but (2, 1) ∉ R. Hence, R is not a symmetric relation. WebExample 1: The relation on the set of integers {1, 2, 3} is {<1, 1>, <1, 2>, <1, 3>, <2, 2>, <2, 3>, <3, 3>} and it is reflexive because <1, 1>, <2, 2>, <3, 3> are in this relation.
