If (R={(a,b):|a-b|<5}) is defined on real numbers, what is true about (R)?

Answer and explanation

Correct answer: It is symmetric

Step 1: For distance, (|a-b|=|b-a|). Step 2: If (|a-b|<5), then (|b-a|<5) also holds. Step 3: Distance-based relations do not have direction, so they are often symmetric.
