let us draw a line segment of length 12 cm with a scale and let\'s measure its parts and verify that they are equal.

AcademicMathematicsNCERTClass 10


Length of the line segment $=12\ cm$.

To do:

We have to draw the line segment, bisect it and measure the length of each part.


Steps of construction :

(i) Draw a line segment $AB = 12\ cm$.

(ii) With centres at $A$ and $B$ and radius more than half of $AB$, draw arcs that intersect each other at $E$ and $F$ on both sides of $AB$.

(iii) Join $EF$ which intersects $AB$ at $D$.


$D$ is the required mid-point of $AB$.

Measuring each part, it is $6\ cm$ long.
