|Example: Construct a line segment of length 4.5 cm.
1. Take a sheet of paper and place a graduated ruler on it.
2. Mark a point 'A' against the zero mark of the ruler.
3. Then mark another point B against the 4.5 mark (4 big divisions and 5 small divisions) on the ruler.
4. Join the points A and B by moving the pencil point along the edge of the ruler from A to B.
Then the line segment AB has a length of 4.5 cm.
Directions: On a sheet of paper construct the following line segments:
1. Line segment BC with a length of 5.6 cm.
2. Line segment PQ with a length of 7.8 cm.
3. Line segment MN with a length of 3.6 cm.
4. Line segment RS with a length of 9.2 cm.
