Detailed explanation-1: -An ellipse and a circle are both examples of conic sections. A circle is a special case of an ellipse, with the same radius for all points. By stretching a circle in the x or y direction, an ellipse is created.
Detailed explanation-2: -In geometry, an ellipse is a two-dimensional shape, that is defined along its axes. An ellipse is formed when a cone is intersected by a plane at an angle with respect to its base. It has two focal points. The sum of the two distances to the focal point, for all the points in curve, is always constant.
Detailed explanation-3: -A closed curve consisting of points whose distances from each of two fixed points (foci) all add up to the same value is an ellipse.
Detailed explanation-4: -Ellipses vary in shape from very broad and flat to almost circular, depending on how far away the foci are from each other. If the two foci are on the same spot, the ellipse is a circle.
