An oval (from Latin ovum 'egg') is a closed curve in a plane which resembles the outline of an 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 of an ellipse.
A stadium is a two-dimensional geometric shape constructed of a rectangle with semicircles at a pair of opposite sides. [1] The same shape is known also as a pill shape, [2] discorectangle, [3] obround, [4] [5] or sausage body. [6] The shape is based on a stadium, a place used for athletics and horse racing tracks.
He defined the oval as the solution to a differential equation, constructed its subnormals, and again investigated its optical properties. [ 8 ] The French mathematician Michel Chasles discovered in the 19th century that, if a Cartesian oval is defined by two points P and Q , then there is in general a third point R on the same line such that ...
A two-dimensional orthographic projection at the left with a three-dimensional one at the right depicting a capsule. A capsule (from Latin capsula, "small box or chest"), or stadium of revolution, is a basic three-dimensional geometric shape consisting of a cylinder with hemispherical ends. [1]

The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane.
For example, the definition of elliptic curve from algebraic geometry is connected non-singular projective curve of genus 1 with a given rational point on it. By the Riemann–Roch theorem , an irreducible plane curve of degree d {\displaystyle d} given by the vanishing locus of a section s ∈ Γ ( P 2 , O P 2 ( d ) ) {\displaystyle s\in ...
Hippopede (red) given as the pedal curve of an ellipse (black). The equation of this hippopede is: + = (+) In geometry, a hippopede (from Ancient Greek ἱπποπέδη (hippopédē) 'horse fetter') is a plane curve determined by an equation of the form
