Conic sections parabola, ellipse, hyperbola, circle. The three types of curves sections are ellipse, parabola and hyperbola. These are the curves obtained when a cone is cut by a plane. Other examples of such curves are parabolas and hyperbolas. Conic sections are mathematically defined as the curves formed by the locus of a point which moves a plant such that its distance from a fixed point is always in a constant ratio to its perpendicular distance from the fixedline.
