Trammel :: Trammel (n.) An instrument for drawing ellipses, one part of which consists of a cross with two grooves at right angles to each other, the other being a beam carrying two pins (which slide in those grooves), and also the describing pencil..

Arc :: Arc (n.) A portion of a curved line; as, the arc of a circle or of an ellipse..

Oblatum :: Oblatum (n.) An oblate spheroid; a figure described by the revolution of an ellipse about its minor axis. Cf. Oblongum.

Spheroid :: Spheroid (n.) A body or figure approaching to a sphere, but not perfectly spherical; esp., a solid generated by the revolution of an ellipse about one of its axes..

Elliptical :: Elliptical (a.) Of or pertaining to an ellipse; having the form of an ellipse; oblong, with rounded ends..

Eccentricity :: Eccentricity (n.) The ratio of the distance between the center and the focus of an ellipse or hyperbola to its semi-transverse axis.

Colligation :: Colligation (n.) That process by which a number of isolated facts are brought under one conception, or summed up in a general proposition, as when Kepler discovered that the various observed positions of the planet Mars were points in an ellipse..

Indicatrix :: Indicatrix (n.) A certain conic section supposed to be drawn in the tangent plane to any surface, and used to determine the accidents of curvature of the surface at the point of contact. The curve is similar to the intersection of the surface with a parallel to the tangent plane and indefinitely near it. It is an ellipse when the curvature is synclastic, and an hyperbola when the curvature is anticlastic..
