May 30, 2021 at 4:57 comment added DKNguyen Seems $v_n$ is supposed to be a magnitude and not a velocity. I was just thinking about pure translation, rotation, and expansion required to maintain the equilateral shape and in all those cases it seems to me the magnitudes of the velocities have to be identical or else distortion would occur. And if it's linear, then superposition you could get combinations of all three motions and the magnitudes still wouldn't change. But that doesn't match any the answers. That's my thinking. This actually sounds more like a math question than a physics question to me.
