If (R) contains only ((1,2)) and ((2,1)), can (R) be called symmetric?

Answer and explanation

Correct answer: Yes, because both are reverses of each other

Step 1: The reverse of ((1,2)) is ((2,1)). Step 2: Both pairs are present, so symmetry is satisfied. Step 3: Diagonal pairs are not compulsory for symmetry.
