Answer 1

Answer:

Reflexive relation.;A relation R on a set A is said to be a reflexive relation if every element of A is related to itself. Thus, R is reflexive iff (x,x)∈R for all x∈A. A relation R on a set A is not reflexive if there is an element x∈A such that (x,x)∉R. For example, consider A=(1,2,3). Then the relation R1 defined by R1={(1,1),(2,2),(3,3),(1,3),(2,1)} is a reflexive relation on A. The relation R2 defined by R2={(1,1),(3,3),(2,1),(3,2)} is not a reflexive relation on A, since (2,2)∉R2. Remark

Every identity relation on a non-empty set A is a reflexive relation, but notconversely. Consider A={a,b,c} and define a relation R by R={(a,a),(b,b),(c,c),(a,b)}. Then R is a reflexive relation on A but not an identity relation on A due to the element (a,b) in R.
