Constructing a Line Segment

We will discuss here about constructing a line segment. We know how to draw a line segment of a certain length. Suppose we want to draw a line segment of 4.5 cm length.

We follow the following steps as given below:

Step I: We place a scale on a paper sheet as shown below.

Step II: We place the sharp point of a pencil on the point which coincides with 0 on the scale and name it as A.

Step III: We mark another point B which coincides with the fifth millimetre division after the 4th centimetre. (1 small division = 1 mm.)

Step IV: We join both points A and B by drawing a line segment with a fine pointed pencil. The line segment AB is of 4.5 cm length.
