- if relation A={1,2}. Is R={(1,1)}a reflexive relation?
if relation A={1,2}. Is R={(1,1)}a reflexive relation?
Answers (1)
As we know,
A relation R in a set A is called reflexive, reflexive, if (a, a)∈R for every a ∈ A.
Here (1, 1) ∈R but there is no (2, 2) present in relation but 2 ∈ A. and hence this relation is not reflexive.
