Question

Draw a line segment of length

6.8

cm using a ruler. Construct another line segment of the same length using a ruler and compass.

Accepted Answer

Given,

The measurement is $6.8 cm$ , we need to draw the line segment of the given length using a ruler and using ruler and compass both.

So, first we will draw the line segment using the ruler.

Take a ruler and mark a point $A$ on the ruler coinciding with $0 cm$ and other point $B$ coinciding with $6.8 cm$ mark.

Join $A$ and $B$ to get the line segment of $6.8 cm$ .

Now, we will draw the line segment of the given length which is $6.8 cm$ using a ruler and a compass.

To construct the line segment we will follow some steps:

(i) Draw a line $l$ and mark any point $A$ on it.

(ii) Place the pointed end of the compass at zero mark of the ruler and open it so that the pencil end reaches $6.8 cm$ mark.

(iii) Without changing the opening of the compass, place the pointed end of the compass at $A$ and draw an arc to cut line $l$ at $B$ .

(iv) $AB$ is the line segment of the required length.

Hence, the above line segment is our required line segment.

Draw a line segment of length $6.8$ cm using a ruler. Construct another line segment of the same length using a ruler and compass.
