Is this relation really transitive?

Question

$$A=\{(0,0),(0,1),(1,0),(1,1),(0,2),(2,0),(2,2)\}$$

Hi guys can somebody tell me why this relation is not transitive? I know that is reflexive and symmetric and also thought that is transitive but my Math-Script say no!

Thanks in advance:)

Answer 1

Hint: $(1,0)$ and $(0,2)$ are in the relation.
