I investigated this using the Venus Synodic Cycle period and plotted with a software how venus is seen from earth in this time during sunrise. The pentagram is FAR from perfect, but it indeed a 5 pointed star. My second investigation was positioning myself 2.2 au from Sun, and also plotting Venus during the same period. This time, there was NO pentagram, since the last point in the 5-pointed star was far off. Am I missing something, or are they?
