Consider the relation R= {(a, b), (a, c), (c, c), (b, b), (c, b), (b, c)} on the set A = {a,b,c}. Is R reflexive? Symmetric? Transitive? If a property does not hold, state why. Let A = {a,b,c,d}. Suppose R is the relation: R= {(a, a), (b, b), (c, c), (d, d), (a, b), (b, a),(a, c), (c, a),(a, d), (d, a), (b, c), (c, b), (b, d), (d, b), (c,d), (d, c)}. Is R reflexive? Symmetric? Transitive? If a property does not hold, state why.
