Answer 1

Answer:

first the common points are 0,1,2 maximum number of common points are 2 . to find a centre of circle is to make to chords and the perpendicular bisector they both meet at point which is known as centre draw the perpendicular of both circles this will make 90 degree angle is perpendicular bisector
