DEF is indeed similar to ABC. Sides 4.5, 15, & 16.5 are 1.5 times their corresponding sides 3, 10, & 11. (GHI is equilateral, and therefore not similar)

I think the student is correct. I'm guessing the question was intending to choose sides so that the triangles are not similar, but accidentally selected a triangle that is similar when flipped.

Thank you for reporting a problem with this exercise. Thisissue has been open for over a week and unfortunately noone has had a chance to look at it yet.

We get close to 100 new issues reported each day, many of which are not real bugs, but simply students having difficulty with the math. Unfortunately this means that even with the assistance of our awesome volunteers, we can't always go through and address each issue individually. Consequently, this issue is being automatically closed.

If you're still experiencing a problem, please report it again! We always keep an eye on the ratio users reporting a problem to users successfully using an exercise, so reporting a problem--even if we can't individually address it--really helps.
