Question

In the parallelogram ABCD, the diagonals AC & BD intersect at O. If OD = 4 cm &

OC = 5 cm. Find AC & BD.​

Answer 1

Answer:

When diagonal AC and BD intersect each other at point o,

then OA = OC = (1/2) AC

And OB = OD = (1/2) BD

∴ OA = 1/2 × AC = 1/2 × 12 = 6 cm

and OB = 1/2 × BD = 1/2 × 9 = 4.5 cm
