The diagonal of a quadrilateral are of lengths 6 cm and 8 cm. If the diagonals bisect each other at right angles, what is the length of each side of the quadrilateral?
We know in rhombus diagonals bisect each other at right angle.
In ΔAOB
BO =
AO =
Using pythagorous theorem in ΔAOB
AB2 = AO2 + BO2
AB2 = 42 + 32
AB2 = 16 + 9
AB2 = 25
AB = = 6cm
Therefore length of each side of a rhombus ABCD is 5cm.
