precisely, a right circular conical surface) with a plane.

Parabola

A parabola is a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. The equation can be x^2=4py, x^2= -4py, y^2=4py or y^2= -4py.

Ellipse

A regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant.

Circle

A round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center). The equation is shown as

(x - h) + (y - k) = r^2
