How do we measure curved lines?

A curved line cannot be measured by a ruler or a straight scale.  A measuring tape or thread must be used instead.

To measure a curved line using a thread, the steps given below should be followed:

  • A knot is tied at one end of the thread.
  • The thread is placed at the beginning of the line and a small initial portion of the line which is relatively straight is measured.
  • A thumb is placed at the other end of the measured portion and the next straighter portion is measured.
  • The above step is repeated till the end of the line is reached. At the end of the line, a knot is made.
  • Now, the thread is straightened and the length of the two knots is measured on a scale.
