(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Which of these relations on {0, 1, 2, 3} are equivalence relations? Determine the properties of an equivalence relation that the others lack

a) { (0,0), (0,2), (2,0), (2,2), (2,3), (3,2), (3,3) }

This one is not reflexive

2. Relevant equations

I understand that reflective means a=a, but I don't understand how this one isn't. I think the real issue here is that I obviously don't understand exactly what reflexive really means.

Any help would be GREAT as I have an exam tomorrow morning and this is proving to be more difficult than I expected.
