What is the conclusion of the statement “if two lines are skew, then they do not lie in the same plane”?

Statement: If two lines are skew, then they do not lie in the same plane.

Conclusion: It's true.

because for any tow lines to be in same plane, either they have to intersect each other or they are parallel.

Ans, Skew lines are those which are not parallel lines and also they do not intersect. 

So, they can never be in one same plane. Thus, the statement is true.
