If (R) is a symmetric relation on a set (A), which statement is true for (R^{-1})?

Answer and explanation

Correct answer: (R^{-1}=R)

Step 1: In an inverse relation, every ordered pair is reversed. Step 2: In a symmetric relation, the reversed pair is already in the same relation, so (R^{-1}=R). Step 3: Remembering the link between symmetry and inverse relation saves time in exams.
