# CLASS-4DRAW A LINE SEGMENT OF GIVEN LENGTH USING A RULER

TO DRAW A LINE SEGMENT OF GIVEN LENGTH USING A RULER - ▪  RULER is used for drawing lines and measuring the length of the line segments.

▪  The ruler is marked in centimeters and inches.

▪  Each centimeter is divided into 10 equal parts. Each part is 1 mm.

To draw a line segment of a given length using a ruler, follow these steps :-

1. Draw a straight line with a ruler that is longer than the given length.
2. Determine the length of the line segment you want to draw, and mark both endpoints of the line segment on the longer line using a pencil.
3. Place the edge of the ruler at one endpoint of the line segment, and line up the 0 point of the ruler with that endpoint.
4. Holding the ruler steady, slide it along the longer line until the other endpoint of the line segment lines up with the correct measurement on the ruler.
5. Draw a line connecting the two endpoints of the line segment using a pencil, and make sure to extend it beyond the endpoints.

By following these steps, you can draw a line segment of any given length using a ruler.

Example.1) To draw a line segment of length of 6 cm. STEPS OF CONSTRUCTION -

a.  Place the ruler on the paper.

b.  Mark a point against the zero mark.

c. Mark another point against the 6 cm mark.

d.  Keep your pencil at the first point and move it along the edge of the ruler keeping the ruler pressed evenly till the pencil reaches the second point.

e.  Remove the ruler and the pencil. Label the points. Thus, the line segment of length 6 cm is drawn.

Example.2) To draw a line segment of length of 10 cm. STEPS OF CONSTRUCTION -

a.  Place the ruler on the paper.

b.  Mark a point against the zero mark.

c. Mark another point against the 10 cm mark.

d.  Keep your pencil at the first point and move it along the edge of the ruler keeping the ruler pressed evenly till the pencil reaches the second point.

e.  Remove the ruler and the pencil. Label the points. Thus, the line segment of length 10 cm is drawn.

Example.3) To draw a line segment of length of 4.5 cm. STEPS OF CONSTRUCTION -

a.  Place the ruler on the paper.

b.  Mark a point against the zero mark.

c. Place your pencil at the 4 cm mark and then count 5 divisions. Mark another point against the 4.5 cm mark.

d.  Keep your pencil at the first point and move it along the edge of the ruler keeping the ruler pressed evenly till the pencil reaches the second point.

e.  Remove the ruler and the pencil. Label the points. Thus, the line segment of length 4.5 cm is drawn.

Example.4) To draw a line segment of length of 6.3 cm. STEPS OF CONSTRUCTION -

a.  Place the ruler on the paper.

b.  Mark a point against the zero mark.

c. Place your pencil at the 6 cm mark and then count 3 divisions. Mark another point against the 6.3 cm mark.

d.  Keep your pencil at the first point and move it along the edge of the ruler keeping the ruler pressed evenly till the pencil reaches the second point.

e.  Remove the ruler and the pencil. Label the points. Thus, the line segment of length 6.3 cm is drawn.
