They are different because since every parallel line is equal it shows that they do not exactly match up because of the transitive property of congruence. These lines never intersect but they don't lie in the same plane so they are not parallel. That makes the two lines parallel. Two lines that intersect at only one point. Statement: Prove, under the assumption of the parallel postulate (P-1), parallelism of lines is transitive. Proof- Assume to the contrary that l … Since K 1 ||K 3 and K 3 ||K 4, again by transitive property, it follows that K 1 ||K 4. If a line $a$ is parallel to a line $b$ and the line $b$ is parallel to a line $c$, then the line $c$ is parallel to the line $a$. The transitive property states that if a=b and b=c then a=c.
