Let l_(1) and l_(2) be the two skew lines. If P, Q are two distinct points on l_(1) and R, S are two distinct points on l_(2) , then prove that PR cannot be parallel to QS.

Let l_(1) and l_(2) be the two skew lines. If P, Q are two distinct points on l_(1) and R, S are two distinct points on l_(2) , then prove that PR cannot be parallel to QS.

Let L be the set of all straight lines in the Euclidean plane. Two line l_(1) and l_(2) are said to be related by the relation R of l_(1) is parallel to l_(2) , Then R is
