a curved line or surface cannot be measured by a straight scale, a measuring tape or thread must be used instead. yo measure a curved line using a thread, follow thr below steps:
• lie a knot at one end of the thread.
• place the thread at the beginning of the line and try to measure a small initial portion of the line which is relatively straight.
• place your thumb at the other end of the measured portion and measure next straighter portion.
• repeat the above step till the end of the line is reached. make a knot at the end of the line.
• now, straighten the thread and measure the length of the two knots on a scale.
