This is a bit of a controversial problem, I'd say: I don't *think* the GMAT can use a term like "perpendicular bisector" without defining it, since perpendicular bisectors (and medians, and angle bisectors, and orthocenters, and centroids, and a host of other fixtures of introductory geometry) are outside of the scope of the problems released so far.
The Grockit problem is hardly controversial.
In fact, it's virtually identical to PS194 in the OG12:

OG 12, from 2009? So the last time this term was used was almost a decade ago?
