In Fig. 7.49, B < A and C < D. Show that AD < BC. Q.3
In the question, it is mentioned that angles B and angle C is smaller than angles A and D respectively i.e. B < A and C < D.
Since the side opposite to the smaller angle is always smaller
AO < BO — (i)
And OD < OC —(ii)
By adding equation (i) and equation (ii) we get
AO+OD < BO + OC
So, AD < BC
