Each circle has two blue points. The intersections of two circles determine a line known as the radical line. The shape of overlapping circles is quite complicated and I'm not sure there is an easier way to specify the shape of intersecting circles than by specifying the two circles. Intersection. The 4 green circles are identical in size (all with radius R) and so are the two rectangles. but if they are, the plane-plane intersection would probably be inconclusive. A tutorial on finding the points of intersection of a circle with a line; general solution. Orthogonal Circles. There are three ways a line and a circle can be associated, ie the line cuts the circle at two distinct points, the line is a tangent to the circle or the line. Mark the intersection points shown below. The line connecting intersection points of two circles is perpendicular to the line connecting their centers. Example 1: Find x in each of the following figures in Figure 2.
