R is not symmetric Check reflexive Check transitive If (a, b) R, then (b, a) R Join Yahoo Answers and get 100 points today. Check Reflexive To check whether transitive or not, Q9: Are symmetry and antisymmetry mutually exclusive? y x is an integer For example, R is defined over set A = {a} as R = {(a, a)}, R is both symmetric and anti-symmetric. where x, y A iv. We say that a is related to a' if (a,a') is in R. A relation can have the following properties: i. Reflexive. Ex 1.1,1(v) d. Is it an equivalence relation? c. Is it a partial order? x z is an integer. using the diagram below: the m
