Answer:

• Relation R on A is defined by R={(1,1)(1,2)(3,3)}The relation R is said to be symmetric, if (a,b) belongs to R then (b,a) should be in R.Here (1,2) is present in R but (2,1) is not present in R.Therefore relation R does not satisfies symmetric condition.Therefore the given relation R is not symmetric.

Hope this helps you ☺️

Please mark me brainliest ☺️...

The Relation R is defined by R = {(1,1) (1,2) (3,3)} for Symmetric

Relation if (1, 2) ∈ R

then (2,1) ∈ R but (2,1) ∉ R?

∴ R is not Symmetric Relation
