Explain the Relation (i) Reflexive `(ii) Symmetric (iii) Transitive`

If R and R' are symmetric relations (not disjoint) on a set A ,then the relation R uu R' is (i) Reflexive (ii) Symmetric (ii) Transitive (iv) none of these

Let n be a fixed positive integer.Let a relation R be defined on Z, as aRb if n is divisible by a-b, then relation R is (i)Reflexive (ii)Symmetric (iii)Transitive (iv) all of these

R_2={(a ,\ a)} is defined on set A={a ,\ b ,\ c} . Find whether or not it is (i) reflexive (ii) symmetric (iii) transitive.

R={(b , c)} is defined on set A={a ,\ b ,\ c} . Find whether or not it is (i) reflexive (ii) symmetric (iii) transitive.

R_(2)={(a,a)} is defined on set A={a,b,c}. Find whether or not it is (i) reflexive (ii) symmetric (iii) transitive.

R_(3)={(b,c)} is defined on set A={a,b,c}. Find whether or not it is (i) reflexive (ii) symmetric (iii) transitive.

For n.m in N,n|m means that n a factor of m, the relation |is- (i) reflexive and symmetric (ii) transitive and symmetric (ii) reflexive, transitive and symmetric (iv) reflexive, transitive and not symmetric

On the set of natural number let R be the relation defined by aRb if 2a +3b=30. Write down the relation by listing all the pair . check whether it is (i) reflexive (ii) symmetric (iii) transitive (iv) equivalence

On the set of natural number let R be the relation defined by aRb if a+b lt=6 . Write down the relation by listing all the pairs. Check whether it is (i) reflexive (ii) symmetric (iii) transitive (iv) equivalence.
