Question

explain the method of measuring the length of a curved line.

Answer 1

A curved line also called an arc represents a portion of a circle. It is difficult to measure a curve with a straight edged ruler with any kind of accuracy but geometry provides a relatively simple way to calculate the length of an arc. You will need a tool called a protractor and some basic information.

Answer 2

Measurement of a curved line

Explanation:

The length of a curved line can be easily measured with the help of a string.

Place the string on the curved line and trace the shape it takes.

Mark the starting point of the line with a knot on the string and the ending point with your thumb.

Now straighten the string and measure the distance between the two points with the help of the ruler which will give the length of the curved line
