### Understanding Conic Sections.

Circles, ellipses, parabolas and hyperbolas are known as conic sections because they can be obtained as intersections of a plane with a double napped right circular cone. A circle is the set of all points in a plane that are equidistant from a fixed point in the plane. The fixed point is called the centre of the circle and the distance from the centre to a point on the circle is called the radius of the circle. A parabola is the set of all points in a plane that are equidistant from a fixed line and a fixed point (not on the line) in the plane. An ellipse is the set of all points in a plane, the sum of whose distances from two fixed points in the plane is a constant.
