Answer 2

There are Four methods of finding relation between the lengths of line segment.

Explanation:

1.Comparison by observation:

• Two line segments AB and CD.
• We can clearly see that line segment $CD > AB$ just by looking. However, if the difference in their lengths is relatively slight, it is not always achievable.

2.Comparison by using a divider:

• A divider is a geometrical instrument having two arms that are linked together at one end by a knob.
• Metallic needles adorn the other ends of the two arms. To compare the supplied line segments AB and CD, we position the needle of one divider hand at point C and carefully open the other arm so that the needle of the other arms lands at point D.
• Now slowly elevate the divider so that the opening of the two arms remains the same. One needle should be placed at point A of line segment AB, while the other arm should be free to fall at any point on AB. There are now three options available to you.
• The other arm falls exactly at B, then $AB = CD$,The other arm falls between A and B, then $AB > CD$.The other end falls away from B, then $AB < CD.$

3.Comparison by Tracing:

• The tracing approach can also be used to compare line segments AB and CD.
• Trace one of the line segments so that point C of the traced segment CD is the same as point A of line segment AB.

4.Measurement of line segments:

• A line segment is a segment that makes up a line. It has a definite length, no breadth, and no thickness, and it has two endpoints.

• A line segment's length is a distance that can be measured in metres, centimetres, millimetres, and other units.

• We use a scale with centimetre marks on one edge and inch marks on the other to measure line segments.
• Keep in mind that each centimetre is divided into ten equal parts, each of which is referred to as a millimetre (mm).
