In this review [v2] I have improved the description of the third characteristic of funicular polygons deriving from the zeta(s) function; I also added a paragraph and an image. For some (probably infinite) values of (s) the function zeta(s) converges on the zero of the complex plane; Riemann called them "non-trivial zeros" and assumed that in all these values of (s) the real part is 1/2. I used a graphical approach to study the first (but sufficient) values generated by the zeta(s) function in the classic version; I also divided the zeta(s) function into its three parts by comparing the results. From the obtained values I have realized on the complex plane of the funicular polygons; in these funicular polygons I have identified three characteristics that indicate with certainty that Riemann's hypothesis is true.
