Then, to combine the two circles into one, set the address of the circle with the larger circumference angle as the address of the new circle, set the two coordinate values that are not the same as the new end point coordinates, leave the radius as it is, and combine the two circles. Let the sum of circumferential angles be the new circumferential angle.
