Let `R` be a relation defined on the set of real numbers by `aRb hArr1+ab>0` then `R` is
(A) Reflexive and symmetric
(B) Transitive
(C) Anti symmetric
(D) Equivalence

Let R be the relation on the set of all real numbers defined by aRb iff |a-b|<=1 .Then R is O Reflexive and transitive but not symmetric O Reflexive symmetric and transitive O Symmetric and transitive but not reflexive O Reflexive symmetric but not transitive

Let R be the relation on the set of all real numbers defined by aRb iff |a-b|<=1 .Then R is Reflexive and transitive but not symmetric Reflexive symmetric and transitive Symmetric and transitive but not reflexive Reflexive symmetric but not transitive

aRb iff 1+ab>0 is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.

Check whether the relationR in the set R of real numbers defined by : R={(a,b):1+abgt0} is reflexive, symmetric or transitive.

Let T be the set of all triangles in the Euclidean plane, and let a relation R on T be defined as a\ R\ b if a is congruent to b for all a ,\ b in T . Then, R is (a) reflexive but not symmetric (b) transitive but not symmetric (c) equivalence (d) none of these

aRb if a-b>0 is defined on the set of real numbers,find whether it is reflexive, symmetric or transitive.
