{{Refimprove|date=June 2012}}&lt;br /&gt;
&lt;br /&gt;
An &amp;#039;&amp;#039;&amp;#039;oval&amp;#039;&amp;#039;&amp;#039; (from Latin &amp;#039;&amp;#039;ovum&amp;#039;&amp;#039;, &amp;quot;egg&amp;quot;) is a [[closed curve]] in a [[plane (geometry)|plane]] which &amp;quot;loosely&amp;quot; resembles the outline of an [[egg (food)|egg]]. The term is not very specific, but in some areas ([[projective geometry]], [[technical drawing]], etc.) it is given a more precise definition, which may include either one or two axes of symmetry.&lt;br /&gt;
In common English, the term is used in a broader sense: any shape which &amp;#039;&amp;#039;reminds&amp;#039;&amp;#039; one of an egg. &lt;br /&gt;
&lt;br /&gt;
The 3-dimensional version of an oval is called an &amp;#039;&amp;#039;&amp;#039;ovoid&amp;#039;&amp;#039;&amp;#039;.&lt;br /&gt;
&lt;br /&gt;
==Oval in geometry==&lt;br /&gt;
[[File:oval1.svg|thumb|right|This oval, with only one axis of symmetry, resembles a chicken egg.]]&lt;br /&gt;
&lt;br /&gt;
The term &amp;#039;&amp;#039;&amp;#039;oval&amp;#039;&amp;#039;&amp;#039; when used to describe [[curve]]s in [[geometry]] is not well-defined, except in the context of [[projective geometry]]. Many distinct curves are commonly called ovals or are said to have an &amp;quot;oval shape&amp;quot;. Generally, to be called an oval, a [[Plane (geometry)|plane]] curve should &amp;#039;&amp;#039;resemble&amp;#039;&amp;#039; the outline of an [[Egg (food)|egg]] or an [[ellipse]]. In particular, the common traits that these curves have are:&lt;br /&gt;
* they are [[curve|differentiable]] (smooth-looking),&amp;lt;ref&amp;gt;When this property makes sense, i.e. when on a differentiable manifold. In more general settings one might only require that there exist a unique tangent line at each point of the curve.&amp;lt;/ref&amp;gt; [[curve|simple]] (not self-intersecting), [[Convex set|convex]], [[curve|closed]], [[plane curve]]s;&lt;br /&gt;
* their [[shape]] does not depart much from that of an [[ellipse]], and&lt;br /&gt;
* there is at least one [[axis of symmetry]].&lt;br /&gt;
Examples of ovals described elsewhere include:&lt;br /&gt;
*[[Cassini oval]]s&lt;br /&gt;
*[[elliptic curve]]s&lt;br /&gt;
*[[superellipse]]&lt;br /&gt;
*[[Cartesian oval]]&lt;br /&gt;
&lt;br /&gt;
An &amp;#039;&amp;#039;&amp;#039;ovoid&amp;#039;&amp;#039;&amp;#039; is the 3-dimensional surface generated by rotating an oval curve about one of its axes of symmetry.&lt;br /&gt;
The adjectives &amp;#039;&amp;#039;&amp;#039;ovoidal&amp;#039;&amp;#039;&amp;#039; and &amp;#039;&amp;#039;&amp;#039;ovate&amp;#039;&amp;#039;&amp;#039; mean having the characteristic of being an ovoid, and are often used as [[synonym]]s for &amp;quot;egg-shaped&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
==Projective geometry==&lt;br /&gt;
[[File:Chicken egg 2009-06-04.jpg|thumb|200px| A chicken egg is a naturally occurring ovoid]]&lt;br /&gt;
&lt;br /&gt;
In the theory of [[projective plane]]s, &amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039;oval&amp;#039;&amp;#039;&amp;#039;&amp;#039;&amp;#039; is used to mean a set of &amp;#039;&amp;#039;n&amp;#039;&amp;#039; + 1  points in a projective plane of order &amp;#039;&amp;#039;n&amp;#039;&amp;#039;, with no three on a common line (no three points are [[line (geometry)|collinear]]).  See [[oval (projective plane)]].&lt;br /&gt;
&lt;br /&gt;
An &amp;#039;&amp;#039;&amp;#039;[[ovoid (projective geometry)|ovoid]]&amp;#039;&amp;#039;&amp;#039; in the finite projective geometry PG(3,q), is a set of &amp;#039;&amp;#039;q&amp;#039;&amp;#039;&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; + 1 points such that no three points are collinear. At each point of an ovoid all the tangent lines to the ovoid lie in a single plane.&lt;br /&gt;
&lt;br /&gt;
==Egg shape==&lt;br /&gt;
The shape of an [[egg (food)|egg]] is approximately half of each of a [[prolate spheroid|prolate]] (long) and a roughly spherical (potentially even slightly [[Oblate spheroid|oblate]]/short) [[ellipsoid]] joined at the equator, sharing a [[principal axis]] of [[rotational symmetry]], as illustrated above.  Although the term &amp;#039;&amp;#039;egg-shaped&amp;#039;&amp;#039; usually implies a lack of [[reflection symmetry]] across the equatorial plane, it may also refer to true prolate ellipsoids.  It can also be used to describe the 2-dimensional figure that, revolved around its [[major axis]], produces the 3-dimensional surface.  Refer to the following equation for an approximation of a 3D egg where the letter &amp;quot;a&amp;quot; represents any positive constant:&lt;br /&gt;
:&amp;lt;math&amp;gt;x^2 + y^2 + z^2(1.5\cos((z+a/2)/a))^2 = a\!&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Technical drawing==&lt;br /&gt;
[[File:Owal by Zureks.svg|thumb|An oval with two axes of symmetry constructed from four arcs (top), and comparison of blue oval and red ellipse with the same dimensions of short and long axes (bottom).]]&lt;br /&gt;
&lt;br /&gt;
In [[technical drawing]], an &amp;#039;&amp;#039;&amp;#039;oval&amp;#039;&amp;#039;&amp;#039; is a figure constructed from two pairs of arcs, with two different [[radius|radii]] (see image on the right). The arcs are joined at a point, in which lines [[tangential]] to both joining arcs lie on the same line, thus making the joint smooth. Any point of an oval belongs to an arc with a constant radius (shorter or longer), whereas in an [[ellipse]] the radius is continuously changing.&lt;br /&gt;
&lt;br /&gt;
==In common English==&lt;br /&gt;
In common speech &amp;quot;oval&amp;quot; means a shape rather like an egg or an ellipse, which may be two-dimensional or three-dimensional. It also often refers to a figure that resembles two semicircles joined by a rectangle, like a [[cricket field|cricket infield]] or [[oval track racing|oval racing track]]. This is more correctly, although archaically, described as [[oblong]].&amp;lt;ref name=&amp;quot;OED, Oblong&amp;quot; &amp;gt;{{Cite book&lt;br /&gt;
  |title=[[Oxford English Dictionary]]&lt;br /&gt;
  |chapter=Oblong&lt;br /&gt;
  |edition=&lt;br /&gt;
  |year=1933&lt;br /&gt;
  |quote=&amp;#039;&amp;#039;&amp;#039;A&amp;#039;&amp;#039;&amp;#039; &amp;#039;&amp;#039;adj.&amp;#039;&amp;#039; &amp;#039;&amp;#039;&amp;#039;1.&amp;#039;&amp;#039;&amp;#039; Elongated in one direction (usually as a deviation from an exact square or circular form): having the chief axis considerably longer than the transverse diameter&lt;br /&gt;
}}&amp;lt;/ref&amp;gt; Sometimes it can even refer to any rectangle with rounded corners.&lt;br /&gt;
&lt;br /&gt;
The shape lends its name to many well-known places (see [[Oval (disambiguation)]]). &lt;br /&gt;
