el·lipse

(ĭ-lĭps′)

1. A plane curve, especially:

a. A conic section whose plane is not parallel to the axis, base, or generatrix of the intersected cone.

b. The locus of points for which the sum of the distances from each point to two fixed points is equal.

2. Ellipsis.

[French, from Latin ellīpsis, from Greek elleipsis, a falling short, ellipse, from elleipein, to fall short (from the relationship between the line joining the vertices of a conic and the line through the focus and parallel to the directrix of a conic) : en-, in; see en-² + leipein, to leave; see leik^w- in Indo-European roots.]

el•lipse

(ɪˈlɪps)

n.

a plane curve such that the sums of the distances of each point in its periphery from two fixed points, the foci, are equal; a conic section formed by the intersection of a right circular cone by a plane that cuts the axis and the surface of the cone. See also diag. at conic section.

ellipse

el·lipse

(ĭ-lĭps′)

A closed, symmetric curve shaped like an oval, which can be formed by intersecting a cone with a plane that is not parallel or perpendicular to the cone's base. The sum of the distances of any point on an ellipse from two fixed points (called the foci) remains constant no matter where the point is on the curve.
