Now let us get back to two lines (Fig. 4.2). Lines that go on forever on either side without meeting each other (i.e. they have a constant distance in between) are called parallel lines.

Now let us get back to two lines (Fig. 4.2). Lines
that go on forever on either side without meeting each other (i.e. they have a constant
distance in between) are called parallel lines.

Thus, parallel lines go forever without meeting.

What will happen if two lines are not parallel?

Then they must meet somewhere! Of course, they go
their way after meeting too.

Here, *l*** _{1}** and

Of course, we now have parallel line segments and
intersecting line segments too.

The position ‘O’ at which the line segments and meet is called their point of intersection.

**Activity**

Take a piece of paper and fold in
as many ways as you can, always generating parallel lines, or always generating
intersecting lines.

A few examples are shown for you.

**Note**

A line has no end points, whereas
a line segment has end points. We can measure the length of a line segment.
