In geometry, an oval or ovoid (from Latin ovum, 'egg') is any curve resembling an egg or an ellipse. Unlike other curves, the term 'oval' is not welldefined and many distinct curves are commonly called ovals. These curves have in common that: In mathematics, the concept of a curve tries to capture the intuitive idea of a geometrical onedimensional and continuous object. ...

Two examples of ovals are shown below. In (a), a semicircle is joined to half an ellipse while in (b), two semicircles are connected with straight line segments. Other ad hoc constructions are often encountered as well. In mathematics, the concept of a curve tries to capture the intuitive idea of a geometrical onedimensional and continuous object. ...

Egg shape
The shape of an egg is approximately an oblate ellipsoid, but, while keeping cylindrical symmetry, as illustrated above, there is not quite symmetry in a plane perpendicular to the long axis. The term eggshaped is typically used taking this asymmetry into account, but it may also simply mean oblate ellipsoid. It can also be used for a 2D shape. 3D rendering of an ellipsoid In mathematics, an ellipsoid is a type of quadric that is a higher dimensional analogue of an ellipse. ...
