WebLet ∼ be a relation on Z defined as follows: For a, b ∈ Z, a ∼ b if and only if 2 divides a + b Is reflexive, symmetric, or transitive? Is it an equivalence relation? Reflexive Symmetric Transitive Equivalence Relation WebDefine reflexive transitive and symmetric relation. Reflexive Relation: A relation R on a set A is called reflexive if ( a, a) ∈ R holds for every element a ∈ A .i.e. if set A = { a, b } then R = { ( a, a), ( b, b) } is reflexive relation.
