When "A" is a subset of "B", is the relation "antisymmetric", "transitive" or "reflexive"?

In set theory we use ARBA\mathcal{R} B to read AA is related to BB or in this case ABA\subseteq B
1) If ARB & BRAA\mathcal{R} B~\&~B\mathcal{R} A does that mean A=B ?A= B~? If so the it is antisymmetric.
2) If ARB & BRCA\mathcal{R} B~\&~B\mathcal{R} C does that mean that ARC ?A\mathcal{R} C~? If so the it is transitive.
3) If for each set ARAA\mathcal{R} A then it is reflexive.
