    R is an "inscribed angle" (it is on the circle) O is a central angle R's arc is QN O's arc is also QN for the same arc, central angles are twice as big as the inscribed angle

    So even if the point R moved, then it would always be twice the angle?

    yes R would always be 1/2 of O, as long as R's arc stays QN

    Maybe you should post it up as a different question. It will be more fair to your answers
