- eccentricity
- Deviation of a conic from a circular shape
- ellipse
- 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
- focus
- fixed point on the interior of a parabola used in the formal definition of the curve
