👉 Circumiterination is a mathematical concept in Euclidean geometry that refers to the relationship between two circles. It describes how the centers of the two circles intersect at one point, forming an ellipse with its major axis as the diameter of the larger circle and its minor axis as the distance from the center of the smaller circle to the point of intersection. In other words, if you have a pair of concentric circles (with each having the same radius), the points where they intersect form an ellipse
