On real numbers, (aRb) when (a^2=b^2). Why is this an equivalence relation?

Answer and explanation

Correct answer: Because it is based on equality and satisfies all three properties

Step 1: (a^2=a^2), so reflexivity holds. Step 2: If (a^2=b^2), then (b^2=a^2), and equality also passes through a chain. Step 3: For equality-based conditions, check the three properties separately.
