Question

Draw a line segment $AB=8cm$ .Draw $3/4$ part of it measure the length of 3/4 part of $AB$ with picture

Answer 1

$AB=8cm$ and so $3/4$ of $AB$ will be $\left(3/4\right)\times 8cm=6cm.$ Steps of construction:

$1.$ Draw a line segment $AB=8cm.$

$2.$Bisect the line segment $AB$ using compass and name the point as $O.$

$3.$ Now, bisect the line segment $AO$ using compass and name the point as $F.$

$4.$ $FB$ is the required line that is $3/4$ of $AB.$

As, $OF=1/4$ of $AB$ as it is half of $AO$ and $OB=1/2$ of $AB.$

So, $FB=OF+OB$

$1/4+1/2=3/4$

$FB=3/4$ of $AB=6cm$
