9.1 Q1 Which of the following figures lie on the same base and between the same parallels. In such a case, write the common base and the two parallels.
8
9.2 Q3 P and Q are any two points lying on the sides DC and AD respectively of a parallelogram ABCD. Show that ar(APB) = ar(BQC).
9
9.2 Q1 ABCD is a parallelogram, AE perp to DC and CF perp to AD. If AB = 16 cm, AE = 8 cm and CF = 10 cm, find AD.
10
9.2 Q4 P is a point in the interior of a parallelogram ABCD. Show that (i) ar(APB) + ar(PCD) = 1/2 ar(ABCD) (ii) ar(APD) + ar(PBC) = ar(APB) + ar(PCD)
