If ABCD is a parallelogram, then prove thatar (ΔABD) = ar (ΔBCD) = ar (ΔABC) = ar (ΔACD) = 12 ar (||gm ABCD)

If ABCD is a parallelogram, then prove thatar (ΔABD) = ar (ΔBCD) = a

1.	If ABCD is a parallelogram, then prove thatar (ΔABD) = ar (ΔBCD) = ar (ΔABC) = ar (ΔACD) = 12 ar (\|\|gm ABCD)
Answer» If ABCD is a parallelogram, then prove that ar (ΔABD) = ar (ΔBCD) = ar (ΔABC) = ar (ΔACD) = $\frac{1}{2}$ ar (\|\|^gm ABCD)
