You observe the fusion at the core of the sun? Why do you make stuff up and try to pass it off as evidence?
It's really tiresome to have to tell you the same things a third time, so why don't you just read up?

There are more, they all converge on the same thing. Until you have a library even a quarter this size, all your claims are weightless.
Hers is one way it is measured.

That assumes a round Earth model to begin with. Of course you are going to get a round Earth measurement.
Wrong, it doesn't assume a round earth. This illustration will show you why:

The Venus-Earth distance was known through radio signals, as it clearly says there, and the distance to the sun is calculated trigonometrically using (distance of Sun-Earth) = (distance of Earth-Venus)*(cosine(angle)), as it clearly states there. You only have to wait until the angle Venus-Earth-Sun is 90 degrees.
