Question

If two lines have no common point can we say they are parallel

Answer 1

Hii friend!!

If two lines have no common point, obviously we can say that the lines are parallel to each other.

We say, any two lines are parallel when the two lines do not intersect or meet at any point.
That is, they do not have any common point.

So, if two lines have no common point, we can say they are parallel.
