# CONSTRUCTION OF LINE SEGMENT

A line segment is the shortest that connects two given points, but a line has no end points.

The line segment joining the two points A and B can be simple written as AB or the line segment AB.

Length of the line segment AB is equal to the length of the line segment BA.

A line segment can be measured either with a ruler or divider.

Let us look at some examples to understand how to construct a line segment.

Example 1 :

Draw a line segment AB  =  5.8 cm using a ruler.

Step 1 :

Draw a line "l" and mark a point A on it. Step 2 :

Fix a ruler on the line. Fix it in such a way that the zero on the scale and the point "A" coincides. Step 3 :

(i) From A, measure 5.8 cm

(ii) Mark the point as B.

(iii) AB = 5.8 cm is the required segment. Example 2 :

With the help of a ruler and compass, draw a line segment PQ  =  2.5 cm

Step 1 :

Draw a line "l" and mark a point P on it. Step 2 :

With the help of a compass, measure 2.5 cm as shown in the figure. Step 3 :

(i) Place the sharp edge of the compass at P.

(ii) Then with the pencil, draw a small arc on "l" to cut the line. mark the point as "Q". (iii) PQ = 2.5 cm is the required line segment.  Apart from the stuff given in this section, if you need any other stuff in math, please use our google custom search here.
