Shatter circle?

Hi Everyone! I am trying to split/trim and obtain the arc built between these two points with a changing angle. Does anybody know how to do it? I tried with shatter yet failed…disposicion radial-prueba (10.0 KB)

you dont need points to build that arc. if you have those points and want to get part of the circle anyway, use curve closest points & shatter.
