Question

The instrument used to compare two line segment is
A.compass
B.divider
C.set square
D.protector

Answer 1

Hint: Here we have to compare two line segments. We will check all the given options . Two line segments are compared using a device having two endpoints known as divider.

Complete step-by-step answer:
Comparing two line segments means finding the shorter or larger line segment.
The methods that compare the length of line segments are as follows.
Comparing using a divider.
Divider is a geometrical instrument which has two arms hinged together with the help of a knob at one end. The other ends of the two arms have metallic needles. To compare the segments, we place the needle of one hand of the divider at one end at the point.
After that lifting the divider. So that opening of the two arms remains unchanged, we have to place one of the needles at A of line segment AB & the other arm if free to fall at any point on AB.
Now, there are three possibilities.
The other arm fall exactly at A then AB = CD
The other arm fall between A & B then AB > CD
The other end falls away from B, then AB < CD

Note: Two line segments are also compared by the method of tracing.
There is one more method of comparison i.e by observation just by observing we can find out that line segment is greater than or lesser than each other. But it is not possible if the difference is very small.
