2018-05-01 00:23
This interactive applet demonstrates the geometric definition of an ellipse by constructing it using two circles. It visually illustrates the fundamental property that the sum of the distances from any point on the ellipse to its two foci is constant. The construction involves geometric objects such as points, circles, circle arcs, segments, orthogonal lines, and loci. It serves as an excellent ed
