Question

The perpendicular bisector of line segment AB meets AB at O. Find the length of AB, if AO = 6.5 cm.

Answer 1

The perpendicular bisector is perpendicular to the line segment and divides it into two equal halves.
$\left[0.5Marks\right]$

$\therefore AO=OB=6.5cm$
$\left[0.5Marks\right]$

From the given figure, we have
$AB=AO+OB$
$\left[0.5Marks\right]$
$\therefore AB=6.5+6.5$
$\Rightarrow AB=13cm$
$\left[0.5Marks\right]$
