Question

Every relation which is symmetric and transitive is also reflexive.

Options

  • True

  • False

MCQ
True or False

Solution

This statement is False.

Explanation:

Let R be a relation defined by

R = {(1, 2), (2, 1), (1, 1), (2, 2)} on the set A = {1, 2, 3}

It is clear that (3, 3) ∉ R.

So, it is not reflexive.
