On (A={1,2,3,4}), (R={(a,b):a^2+b^2=10}). What type of relation is (R)?

Answer and explanation

Correct answer: Symmetric

Step 1: If (a^2+b^2=10), then (b^2+a^2=10) as well. Step 2: Hence ((a,b)) comes with ((b,a)). Step 3: The sum is unchanged when the order is reversed, so the relation is symmetric.
