ellipse
IPA: ɪɫˈɪps
noun
- (geometry) A closed curve, the locus of a point such that the sum of the distances from that point to two other fixed points (called the foci of the ellipse) is constant; equivalently, the conic section that is the intersection of a cone with a plane that does not intersect the base of the cone.
- A park in Washington, District of Columbia, United States
- Synonym of President's Park South, a 52 acre city park, south of the South Lawn of the White House, between the White House estate and the Washington Monument grounds of the National Mall.
- An elliptical oval grassy field in President's Park South
verb
- (grammar) To remove from a phrase a word which is grammatically needed, but which is clearly understood without having to be stated.

- By measuring the position angle of the companion star relative to the primary and the angler distance between the two stars over time, the ellipse, called the apparent ellipse, which is the orbit of the secondary in respect to the primary, can be plotted out.
- These foci are equidistant from the centre of the ellipse, which is formed as follows: Two pins are driven in on the major axis to represent the foci A and B, Figure 75, and around these pins a loop of fine twine is passed; a pencil point, C, is then placed in the loop and pulled outwards, to take up the slack of the twine.
- Two pins are stuck through a sheet of paper on a board, the point of a pencil is inserted in a loop of string which passes over the pins, and as the pencil is moved round in such a way as to keep the string stretched, that beautiful curve known as the ellipse is delineated, while the positions of the pins indicate the two foci of the curve.
