An ellipse is a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant, or resulting when a cone is cut by an oblique plane that does not intersect the base.

Ellipse Haikus:

I am an ellipse
I am a perfect oval
I am a conic

An oval-like shape
A stretched circle's what I am
A comet's orbit

-Nick Bennett

Three Haikus for Dan
Extra credit is hoped for
I could use it now

-Nick Benentt
