In constructing the circle by means of a thread, we had to hook the closed thread around a fixed poinr, the center and keep it stretched while drawing the circle. We obtain a similar curve if we keep the closed thread stretched around two fixed points. This curve is called an ellipse, and the two fixed points are called its foci, The thread construction characterizes the ellipse as the curve with the property that the sum of the distances from two given points to any point on the curve is constant. If the distance between the two points is diminished until the points coicide, we obtain the circle h ellipse rctle as a limiting case of the ellipse.
All the best to you.
