if a relation is reflexive, symmetric, or transitive А = {1, 2, 3, 4}
p= {(1, 1), (2, 2), (3, 3), (4, 4), (1, 3), (3, 4)}
I know what reflexive, symmetric, or transitive are, I just want answer with these examples.
I think it should be transitive?

It is reflexive 
$(a,a)$ for all $a\in A$
It is not symmetric as $(1,3)$ is in $p$ but $(3,1)$ is not.
It is not transitive.  If it were then $(1,3), (3,4) \implies(1,4).$
But that is not the case.
