Question

In the given relation determine the properties( reflexivity, symmetry, transitivity), which ones the relation has: r = {(1,1),(2,2),(3,3),(1,2)}

Answer 1

Relation R is reflexive as (1,1) , (2,2) , (3,3) € R

Relation R is not reflexive as (1,2) € R but ( 2,3) doesnt belong to R

Relation R is transitive
as (1,1) €R and (1,2)€R => (1,2)€R and
(1,2)€R and (2,2)€R => (1,2)€R
