This approach is one way to construct ellipses. Allowing the construction of an ellipse given its directrix, focus, and eccentricity is another. These two approaches will be shown to allow the same constructions. 2.

Ellipses appear in descriptive geometry as images (parallel or central projection) of circles. There exist various tools to draw an ellipse. Computers provide the fastest and most accurate method for drawing an ellipse. However, technical tools (ellipsographs) to draw an ellipse without a computer exist. The principle of ellipsographs were known to Greek mathematicians such as Archimedes and Proklos. corona test zwenkau apotheke
