Description
Cutting a cone by a plane yields several different curves of second degree, which are known as conic sections. This white plaster model of a circular cone has three parts. One is fixed to the base. A second and the largest is cut by a plane on one side to give a hyperbola and on the other side to give an ellipse. The third piece, on the other side of the piece attached to the base, reveals a parabola when cut away. A fourth piece, which attaches to the ellipse, is missing. This example has no labels.
