then all the circles of the system intersect in the same two points, andany circle of the system is then obtained by taking a point O3 on theline of centres as centre, and the length of the straiglit line joiningthis point to the point P or Q as radius. The circles are then saidto be of the… … Fig. 2. If 0 be the point of intersection of the radical axis and the line ofcentres, the length of the tangent drawn to every circle of the systemfrom 0 is the same. If a circle be drawn with centre O, and radiusequal to the tangent, OTj or OTq, drawn to the two given circles asradius, the points…
