Question

Why is it better to use a divider than a ruler, while measuring the length of a line segment?

Answer 1

Hint: Generally smaller line segments are measured using a centimeter scale and Divider is an instrument for measuring, transferring, or marking off distances, consisting of two straight adjustable legs hinged together and each with a sharp point. Ruler is a tool used to rule straight lines and measure distances and this ruler is marked in cm (centimeters).

Complete step-by-step answer:
When we measure the length of a line segment by a ruler, there may be some errors due to its thickness and angular viewing and these errors can be removed by measuring a line segment with the help of a divider. Hence, it is better to use a divider than a ruler, because the thickness of the ruler may cause difficulties in reading off the length. However, the divider gives up accurate measurement. Therefore, it is better to use a divider than a ruler, while measuring the length of a line segment.

Dividers are one of the earliest and most basic types of mathematical instruments. In their simplest form, dividers consist of a jointed pair of legs, each with a sharp point. They can be used for geometrical operations such as scribing circles but also for taking off and transferring dimensions.

Note: A divider has a small pointer on both itself so when you keep the pointer on two edges and then keep the pointer on the ruler you will get an appropriate measure instead of directly using the scale as it is not that clear when you keep it directly and measure you may not get the accurate value of the measurement.
