## Point

a feature of an animal’s physical qualities used in evaluating an animal’s body conformation, breed traits, age, sexual development, health, productivity or performance, and breeding value. The points of an animal are considered collectively and in relation to one another. Different points are distinguished for different animal species and for the evaluation of different forms of productivity. A general evaluation is reached by adding up the points.

The principal points of a horse are shown in Figure 1.

## Point

a fundamental concept in geometry. In systematic expositions of geometry, the point is usually regarded as one of the primitive concepts. In modern mathematics the elements of various spaces are called points. In n-dimensional Euclidean space, for example, a point is an ordered set of *n* numbers. The points of different spaces may be of a very different nature.

Points having special names are encountered in many areas of mathematics. In geometry, for example, the singular points of curves may be studied. Such points include cusps, isolated points, points of inflection, natural boundary points, nodes, points of osculation, and corner points. Mathematical analysis deals with such singular points as critical points of differential equations and singularities of analytic functions. In set theory, a number of points characterizing the properties of a given set have received special names—for example, limit points, density points, and boundary points.

## point

There are six slightly different definitions: Truchet point, Didot point, ATA point, TeX point, Postscript point, and IN point.

In Europe, the most commonly used is Didot and in the US, the formerly standard ATA point has essentially been replaced by the PostScript point due to the demise of traditional typesetting systems and rise of desktop computer based systems running software such as QuarkXPress, Adobe InDesign and Adobe Pagemaker.

There are 20 twips in a point and 12 points in a pica (known as a "Cicero" in the Didot system).
