Question #257

There are two straight lines, which intersect. Can we draw a straight line which doesn’t belong to the plane, to which given lines belong, through the intersection point? Explain your answer.

Expert's answer

Yes, we can, because we can draw an infinite number of straight lines through a point in space and (according to the third theorem of stereometry) if two different lines have a common point, then through them can be built a plane, and only one.
