    Distance from the origin O to the line E calculated with the Hesse normal form. Normal vector in red, line in green, point O shown in blue. In analytic geometry , the Hesse normal form (named after Otto Hesse ) is an equation used to describe a line in the Euclidean plane R 2 {\displaystyle \mathbb {R} ^{2}} , a plane in Euclidean space R 3 ...

  6. Normal (geometry) - Wikipedia

    en.wikipedia.org/wiki/Normal_(geometry)

    In geometry, a normal is an object (e.g. a line, ray, or vector) that is perpendicular to a given object. For example, the normal line to a plane curve at a given point is the line perpendicular to the tangent line to the curve at the point. A normal vector of length one is called a unit normal vector.

  7. Plane (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Plane_(mathematics)

    In mathematics, a plane is a two-dimensional space or flat surface that extends indefinitely. A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space. When working exclusively in two-dimensional Euclidean space, the definite article is used, so the Euclidean plane refers to the ...

  9. Normal plane (geometry) - Wikipedia

    en.wikipedia.org/wiki/Normal_plane_(geometry)

    The normal section of a surface at a particular point is the curve produced by the intersection of that surface with a normal plane. [1] [2] [3] The curvature of the normal section is called the normal curvature. If the surface is bow or cylinder shaped, the maximum and the minimum of these curvatures are the principal curvatures.
