Line segment C

A line segment is a part of a line. It has two end Think and Answer

points. A line segment has a definite length.
List the objects that
So, it can be measured as well as drawn. Here, in D represent a line segment.
the given figure, a line segment is shown whose

end points are C and D. The line segment CD is denoted by CD or DC.
measuring a Line segment

We use a centimetre ruler to measure line segments. The distance between two
consecutive numbers on this scale is 1 cm.

Let us measure the length of the given line segment, AB using a ruler.

A B

We use the following steps:

Step 1: Place the scale along the line

segment in such a way that the one On a ruler, there are ten small markings

end of the line segment coincides between two consecutive numbers. Each
with the zero mark on the ruler. small marking represents a millimetre
1
Step 2: Read the measure on the scale (mm), so, 1 mm = 10 cm = 0.1 cm. For
aligned with the other end. The example, between 7 and 8 the markings
show 7.1, 7.2, …, 7.8, 7.9 (in cm).
reading gives the length of the
segment.

Here, A is at 0 mark and B aligns with the 7th division after 7. So, the length

of the line segment AB is 7.7 cm.
A 7.7 cm B

Drawing a Line segment

We use a sharp pencil and a ruler to draw a line segment of given length.

Let us draw a line segment of length 6.8 cm by following the given steps.

Step 1: Mark a fine dot with a pencil on a sheet of paper. Name it point A.
