let be ABCD Is a quadrilateral and AC and BD are the diagonal and it bisect each other at right angle at O.
such that
AO = OC
OB= OD
we have
AC= 16cm
OA= 8 cm.=OC
BD= 12cm.
OB= OD= 6cm.
in ∆AOB
(AB)²= OA²+ OB²
AB²= 8²+6²
AB²=64+36
AB²= 100
AB= √100
AB= 10cm.
hence the side of quadrilateral is 10cm.and it is rhombus so all sides are 10cm.
