Q: 5 In Fig. 9.17, PQRS and ABRS are parallelograms and X is any point on side BR. Show that
(i) Parallelogram PQRS and ABRS are on the same base RS and between the same parallels RS and PB.
(ii) AXS and ||gm ABRS are on the same base AS and between same parallels AS and RB.
Therefore, ar (AXS) = 1/2 . ar(||gm ABRS)............(ii)
Now, from equation (i) and equation (ii), we get
