Examples of connected dots?

[ReneZ]

The faces form greek letters rotated in different degrees: pi, ro, chi and gamma.

I do like the general idea. Note, however, that gamma is a mirror image.

Chi has a similar sound as latin i (please, greek expert needed ) 

No Greek expert here, but that is certainly not correct.

Perigee nowadays is a type of apsis, an extreme point in an object's orbit. 

I dont know if the meaning or perigee in the time when the ms was written was the same than now.

This is absolutely out of the question. The idea that orbits were not circular, but elliptical (and thus have a periapsis), was born with Kepler, almost 200 years after the writing of the Voynich MS.
