Question

A curved line can be measured using a thread

Answer 1

Answer:

Yeah, a curved line can be measured using a thread because it can't be measured by a plastic scale or a steel or a wooden scale..

Answer 2

Answer:

A curved line or surface cannot be measured by a straight scale, a measuring tape or thread must be used instead.To measure a curved line using a thread, follow the below steps:

• Tie 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 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.
