Best ResponseYou've already chosen the best response.1oh!! that would be crystal clear. Are the midpoints of chords subtending 2pi/3 at center?

Best ResponseYou've already chosen the best response.0@@experimentX you misunderstood. it says the locus of mid points of all those chords, which subtend angle 2pi/3 at center the chord subtends angle 2pi/3 at the center..

Best ResponseYou've already chosen the best response.0Last thing,what will be the radius of the circle(i.e locus) of midpoint of chords?OM?why?
