thats easy.... extend lines from the points of the larger object towards the smaller object make sure that they touch the same point in the smaller object then all of those lines will intersec each other ... so thus that will be ur centre and to find the scale see what they ask you like from smaller to bigger or bigger to smaller so to do so... u find the length of one side of the bigger one and divide it by the length of the same side of the smaller one!
