The question is incomplete, because "the following" was not provided.
A circle, however, is a conic section where the sectioning plane is perpendicular to the cone's axis of symmetry and intersects each generator or, more specifically, if it is not a right circular cone, parallel to the generating circle of the cone.
Yes.
No, a circle is defined as a closed plane curve.It neither has a beginning or a finish.
Circle
Any closed figure that is not entirely composed of straight sides, such as an ellipse or a circle.
A shape cannot have only one side because it would not be closed. A shape must have at least three sides to be a closed figure (no "gaps")
An ellipse is a conic section which is a closed curve. A circle is a special case of an ellipse.
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.
Ellipse and curve! apex

If points on the circumference are excluded from the locus then an open circle, else a closed one.
If the inequality is > or< then it is an open circle. If it is greater than or equal to or less than or equal to, it is a closed circle.
