As you know, we have learnt the basic concept of Geometry like point, line, line segments, ray,
types of lines, open and closed figures and how to measure/draw a line segment of integer
number length in previous class. Now with the help of this chapter we will learn how to
draw/measure the line segment of fractional number length and many more.

Pair of Lines
Parallel lines: The lines on a plane that never meet, no matter how far they are extended, are
called parallel lines. They are always the same distance apart and are represented with a pair
of vertical lines (‖) between the names of the lines.
