On real numbers, (R={(a,b):a^2+b^2=1}). Which statement about (R) is correct?

Answer and explanation

Correct answer: It is symmetric

Step 1: Reversing (a) and (b) changes (a^2+b^2=1) to (b^2+a^2=1). Step 2: By commutativity of addition, this is the same condition. Step 3: For algebraic conditions, check whether the equation remains unchanged after swapping variables.
