i think it is A... could someone please check?

btaylor · Answer

They are not similar because BR;BD=1:2 and KE:KY=1:5 
The answer is C.

anonymous · Answer

Could you please explain? @BTaylor 
i understand how to get BR"BD =1:2 but not KE:KY

btaylor · Answer

using the distance formula:$$d=\sqrt{(x_2-x_1)^2 + (y_2 - y_1)^2}$$
you get KE = 1.41 and KY = 7.07, a 1:5 ratio.
