On the set of all circles, (C_1RC_2) if and only if the two circles have the same radius. What type of relation is this?

Answer and explanation

Correct answer: Equivalence relation

Step 1: The radius of any circle is equal to itself. Step 2: If the first circle has the same radius as the second, the reverse is also true. Step 3: Equality of radius is transitive, so this is an equivalence relation.
