Circles, ellipses, parabolas, and hyperbolas are called conic sections because they can be obtained as a intersection of a plane with a double- napped circular cone.
If the plane passes through vertex of the double-napped cone, then the intersection is a point, a pair of straight lines or a single line. These are called degenerate conic sections.
Because they are sections of a cone or a cone shaped object.

Why are conic sections called conic?
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.
What are the six conic sections?
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.
Which Conic sections describes a closed curve?
Circles, parabolas, ellipses, and hyperbolas are all conic sections. Out of these conic sections, the circle and ellipse are the ones which define a closed curve.
When a circle shape is cut form a cone it is called a what section?
When a circle shape is cut from a cone, it is called a conic section. Conic sections are formed by the intersection of a plane with a cone. Depending on the angle and position of the plane, the conic section can take the form of a circle, ellipse, parabola, or hyperbola. Each type of conic section has unique mathematical properties and equations that describe its shape.
