The distances from the earth were infered to be in a linear form, with th earth in the center. Therefore the galaxies are in there gretest distance from eachother, in relation to that moment in time.

the distance from Earth is liner to each of the galaxies in question, but not necessarily are the Earth and each galaxy colinear. could be a triangle formation, which is my point.

whilst three points define a plane, there's a fourth to consider: the Origin. So now we move from 2 to 3 dimensions. Nowhere in the suppositions given did I see that the Origin, earth and two galaxies are coplanar. therefore they need not be. And that triangle emerges again.
