Let's assume choice A is the answer (it may or may not be)

If choice A was the answer, then dividing the corresponding side lengths should give us the same number

So 22/11 = 2 but 27/16 = 1.6875 so choice A is NOT a similar triangle with the given triangle

notice how 33/11 = 3 48/16 = 3 66/22 = 3 so we're tripling each given side to get the new corresponding side
