1 112 is it reflexive symmetric antisymmetric or transitiveS

{(1, 1),(1,2)} is it reflexive, symmetric, antisymmetric, or transitive

Solution

it is not reflexive since (2,2) is not there.

it is not symmetric because (2,1) is not there.

It is transitive since (1,1) -> R and (1,2) -> R, then (1,2) should belong to R which is true where R is the relation.

it is not antisymmetric since (2,1) is missing.
