It would have been nice if the answer choices had a similarity symbol
after each answer choice. I think most students equate AA, SAS, SSS, ASA with
AA = AA, SAS = SAS, SSS = SSS, ASA = ASA (I'm using equals to represent
congruent). The first answer makes sense, but choices 2 and 3 do not and
therefore should be written as SAS~ or SSS~.

With that said, there is nothing wrong with the question, but I doubt most
of our students will answer it correctly as SAS~ and SSS~ appear
infrequently in our study of similarity.

But then again, the question is consistent with most of the exam (Read
#38) where one minute concept that is given fairly little weight in the grand
scheme of the curriculum appears on a high stakes exam. I guess it's my
own fault, but median, the division postulate and overlapping triangles are
not high on my list of priorities when I spend month after month teaching
every possible proof that's ever been in existence.

Good thing I emphasized the need to be an expert in the equation of a
circle though.
