Consider binary relations on the set A={1,2,3,4,5}. Are the following relations reflexive? Symmetric? Antisymmetric? Transitive? 1. R1={(1,2),(3,4),(4,5),(3,5),(2,2),(3,3),(4,4)} 2. R2={(1,2),(2,3),(4,5),(5,1)} 3. R3={(3,1),(1,3),(4,5)} 4. R4={(1,1),(1,5),(2,2),(2,4),(3,3),(4,2),(4,4),(5,1)} 5. R5={(1,1),(5,1),(2,3),(3,2),(3,3),(4,4),(5,1)}
