Question 11

Q11) In parallelogram ABCD, its diagonals intersect at point O. If OA = 6 cm and OB = 7.5 cm, find the length of AC and BD.

Solution:

When diagonal AC and BD intersect each other at point O.

OA=OC=\frac{1}{2}AC

OB=OD=\frac{1}{2}BD

OA=\frac{1}{2}\times AC>AC=\ 2\ \times OA>AC=\ 2\times6=12\ cm

and OB=\frac{1}{2}\times BD>BD=\ 2\ \times OB>BD=\ 2\times7.5=15\ cm
