Ellipse /ɪˈlɪps/


In mathematics, an ellipse (from Greek ἔλλειψις elleipsis, a “falling short”) is a plane curve that results from the intersection of a cone by a plane in a way that produces a closed curve. Circles are special cases of ellipses, obtained when the cutting plane is orthogonal to the cone’s axis. An ellipse is also the locus of all points of the plane whose distances to two fixed points add to the same constant. The name ἔλλειψις was given by Apollonius of Perga in his Conics, emphasizing the connection of the curve with “application of areas”. (http://en.wikipedia.org/?title=Ellipse)

Ellipse (math is fun)

  1. • How can you draw an ellipse by arc of circle method when major axis is 120 mm and minor axis is 80 mm?
  2. • How can you draw an ellipse by ellipse – arcs of circles method when major radius is 50 mm and minor radius is 30 mm?
