circle and ellipse are closed curved conic section!, from bilal , Pakistan
A conic section is the intersection of a plane and a cone. By changing the angle and location of intersection, we can produce a circle, ellipse, parabola or hyperbola; or in the special case when the plane touches the vertex: a point, line or 2 intersecting lines.Traditionally, the three types of conic section are the hyperbola, the parabola, and the ellipse. The circle is a special case of the ellipse, and is of sufficient interest in its own right that it is sometimes called the fourth type of conic section.
A conic section is a curve formed by the intersection of a plane with a cone (conical surface). If the section is parallel to the base of the cone, the conic section has a fixed diameter and is a circle. Any other plane that does not intersect the apex is either a parabola, a hyperbola, or an ellipse.
Due to most conventional way for writing functions (two parts) that represents a ellipse is (x - a)^2 / c + (y - b)^2 / d = 1, which is similar to those of conic functions (hyperbolas) where + is replaced with - in the middle. Yet you can think of -d replaces d.
They are the shapes of the slices when you slice a cone. For example, when you slice it parallel to the base and look at the shape of the slice, you see the conic section known as a "circle". The others are the "ellipse", the "parabola", and the "hyperbola". Which one you get depends only on how you tilt the knife when you slice the cone.
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.

No, a conic section does not have vertices. If it is a circle, it has a center; if it is a parabola or hyperbola, it has a focus; and if it is an ellipse, it has foci.

An ellipse is a conic section, a curving line which is the path of a point that moves in such a way that the sum of its distance from two fixed points is constant.... so no - there are not 4 straight angles in an ellipse, nor any straight bits at all.

Newton showed that any two objects in space (eg. two planets) whose movement is controlled by gravity will move in a conic section relative to one another. That is why the Earth moves around the sun in an ellipse.
