noun Geometry.

a plane curve such that the sums of the distances of each point in its periphery from two fixed points, the foci, are equal. It is 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. Typical equation: (x2/a2) + (y2/b2) = 1. If a = b the ellipse is a circle.

Origin of ellipse

1745–55; <French <Latin ellīpsisellipsis; or by back formation from the plural ellipses

Cultural definitions for ellipse

ellipse

[ (i-lips) ]

In geometry, a curve traced out by a point that is required to move so that the sum of its distances from two fixed points (called foci) remains constant. If the foci are identical with each other, the ellipse is a circle; if the two foci are distinct from each other, the ellipse looks like a squashed or elongated circle.

notes for ellipse

The orbits of the planets and of many comets are ellipses.

Scientific definitions for ellipse

ellipse

[ 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.
