A line can be named either using two points on the line or simply by a letter. There is a lot of difference between the line and line segments. We can measure the length of the line segment but not a line. The instruments used to measure the length of a Line-segment are scale and divider. This article helps you to know how to measure the length of a line segment using a ruler scale and divider. Practice the questions given at the end of this page to enhance your skills.

Line Segment – Definition
If you Mark two points A and B on a straight line is called the line segment. This line segment has two endpoints A and B whose length is fixed. The length of a line segment is the distance between two endpoints. The length of a line segment can be measured by millimeters, centimeters, meters, and feet or inches.
How to Measure the Length of a Line Segment?
We can measure the length of the line segment by using two methods:
i. With the help of scale or ruler only.
ii. With the help of a pair of dividers and scale or ruler.
How to Measure Line Segments with a Ruler?
Step 1: pick up a scale to measure the length of a line segment. Generally smaller line segments are measured using a centimeter scale.
Step 2: Identify the line segment that you want to measure.
Step 3: Place the tip of the ruler at the starting point of the line segment.
Step 4: Read a number on the scale where the line segment ends in this case, it is 7 so the length of the given line segment is 7 cm.
How to Measure the Length of a Line Segment with a Divider?
We can measure the length of a line segment with scale and divider.
i. First open the pair of dividers carefully and place the pointed ends of the pair of dividers on both ends of the line segments.
ii. Next we lift the divider without disturbing the arms.
iii. And then place its one end on the zero mark of the scale.
Measuring Length of a Line Segment Examples
Example 1.
How to draw the line segment of a given length is 6 cm?
Solution:
First, Pick up a scale to measure the length of a line segment.
Identify the line segment that you want to measure. We have to measure the length 6 cm on the scale.
Place the tip of the ruler at the starting point of the line segment.
Read a number on the scale where the line segment ends in this case, it is 6cm so the length of the given line segment is 6 cm.
Example 2.
How to draw the line segment of the given length is 4 cm?
Solution:
i. First open the pair of dividers carefully and place the pointed ends of the pair of dividers on both ends of the line segments i.e., from 0 to 4.
ii. Next we lift the divider without disturbing the line.
iii. And then place its one end on the zero mark of the scale.
Example 3.
How to draw the line segment of the given length is 12 cm?
Solution:
First, Pick up a scale to measure the length of a line segment.
Identify the line segment that you want to measure. We have to measure the length 6 cm on the scale.
Place the tip of the ruler at the starting point of the line segment.
Read a number on the scale where the line segment ends in this case, it is 12 cm so the length of the given line segment is 12 cm.
Example 4.
How to draw the line segment of the given length is 3 cm?
Solution:
First, Pick up a scale to measure the length of a line segment.
Identify the line segment that you want to measure. We have to measure the length 6 cm on the scale.
Place the tip of the ruler at the starting point of the line segment.
Read a number on the scale where the line segment ends in this case, it is 3 cm so the length of the given line segment is 3 cm. 
Example 5.
How to draw the line segment of the given length is 16 cm?
Solution:
First, Pick up a scale to measure the length of a line segment.
Identify the line segment that you want to measure. We have to measure the length 6 cm on the scale.
Place the tip of the ruler at the starting point of the line segment.
Read a number on the scale where the line segment ends in this case, it is 16 cm so the length of the given line segment is 16 cm.
FAQs on How to Draw & Measure Line Segments
1. How do you find the length of the line segment?
The length of a line segment can be measured by measuring the distance between the two endpoints.
2. What is used to measure line segments of length?
We can measure a line segment with the help of a ruler scale or divider.
3. Which instrument is used to measure a line segment?
The instrument used to compare two line segments is a divider.
