O is the mid point of BC
so let B(x,y)
so
0=(x+0)/2   and   0 = (y-3)/2.......midpoint formula
x= 0 and y = 3
B=(0,3)
now we can find co ordinates of A 
using distance formula
AB = AC.......eqn.1
AB = BC......eqn.2
now D and D' are the two possible ways to construct the required rhombus.
suppose A(x,y)
now after finding A
use distance formula to find AD distance since AD = BC and AD = AB
also D' is possible too
use same method to find D'
