1. Consider any . We want to show that ~ using the other two properties of equivalence relations. 2. The symmetric property says that for any y, x~ y⇒y~x. 3. Since ~ y and y, the transitivity property implies that ~ x. 4. Therefore from symmetry and transitivity we have reflexivity. Is this proof correct? a) This proof is correct. b) This proof is first incorrect in step 1. c) This proof is first incorrect in step 2.

Claim: In the definition of an equivalence relation ~, the reflexivity of ~ is redundant. Proof. 1. Consider any . We want to show that ~ using the other two properties of equivalence relations. 2. The symmetric property says that for any y, x~ y⇒ y~ x. 3. Since ~ y and y~ x, the transitivity property implies that ï ~ X. 4. Therefore from symmetry and transitivity we have reflexivity. Is this proof correct? a) This proof is correct. b) This proof is first incorrect in step 1. c) This proof is first incorrect in step 2.
