Conic Sections

A cone is a pyramid with a circular base (345:1), and a vertical cut through the axis will yield a section which is a triangle, parallel to the axis a

hyperbola, and parallel to one of the sides a parabola. If the cut is parallel with the base then the section will be a circle (345:2), and inclined to the base an ellipse. Of these conic sections the ellipse is of considerable importance in the setting out of oval-shaped work, gate-leg tables, etc., and although it can be drawn by hand it is more satisfactory to construct it geometrically.
