Plot and plot are wrong at geometry demos

[Jaime02]

Hello, I was trying to plot a geometric regular polygon looking at this demo:

https://docs.sympy.org/latest/modules/plotting.html#plot-geom

I have found errors importing Plot and plot, in the web site the live demos does not work, please somebody fix them. Most of the demos are broken.
