2. Place the  thread along the line.
 
3. Mark the points where the line  on the thread.
 
4. Keep the thread on the .
 
5. Measure the between the thread marks.
 
Method 2:
 
1. Draw a  \(AB\) on a paper.
 
2. Using a , separate the by \(0.5\ cm\) or \(1\ cm\).
 
3. Place the on the line from one end to the other.
 
4. Move the  divider along the line again.
 
5. Cut the line into and keep a .
 
6. If there is any remaining part of the line, measure it using a .
 
Therefore, the length of the line is given by
 
 \(\times\)
