mathematics, a projective plane is a geometric structure that extends the concept of a plane. In the ordinary Euclidean plane, two lines typically intersect...

In analytic geometry, the intersection of a line and a plane in three-dimensional space can be the empty set, a point, or a line. It is the entire line...

analytic geometry, the intersection of two planes in three-dimensional space is a line. The line of intersection between two planes Π 1 : n 1 ⋅ r = h 1 {\displaystyle...

In geometry, an intersection is a point, line, or curve common to two or more objects (such as lines, curves, planes, and surfaces). The simplest case...

Outer Plane is one of a number of general types of planes of existence. They can also be referred to as godly planes, spiritual planes, or divine planes. The...

In mathematics, a plane curve is a curve in a plane that may be a Euclidean plane, an affine plane or a projective plane. The most frequently studied cases...

arise when the intersection of the cone and plane is a closed curve. The circle is obtained when the cutting plane is parallel to the plane of the generating...

algebraic plane curve is the zero set of a polynomial in two variables. A projective algebraic plane curve is the zero set in a projective plane of a homogeneous...

geometry, the Poincaré half-plane model is a way of representing the hyperbolic plane using points in the familiar Euclidean plane. Specifically, each point...

horizontal plane. For a plane, the two angles are called its strike (angle) and its dip (angle). A strike line is the intersection of a horizontal plane with...

projective plane cannot be embedded (that is without intersection) in three-dimensional Euclidean space. The proof that the projective plane does not embed...

where the plane intersection meets σ or the line at infinity. Thus the axiom of projective geometry, requiring all pairs of lines in a plane to intersect...

In finite geometry, the Fano plane (named after Gino Fano) is a finite projective plane with the smallest possible number of points and lines: 7 points...

plane of a revolving body is the geometric plane in which its orbit lies. Three non-collinear points in space suffice to determine an orbital plane....

meridian plane in this axial-pencil through that location. The intersection of this plane with Earth's surface defines two geographical meridians (either...

A tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called tiles, with no overlaps and no gaps....

gallbladder projects from the liver's inferior border at the intersection of the transpyloric plane and the right lateral midline. Despite the right kidney...

science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces...

intersecting planes or half-planes. It is a plane angle formed on a third plane, perpendicular to the line of intersection between the two planes or the common...

The ecliptic or ecliptic plane is the orbital plane of Earth around the Sun. It was a central concept in a number of ancient sciences, providing the framework...

there is only one plane, while in three dimensions all planes have at least one nonzero vector in common, along their line of intersection. In more than three...

(from oculus), a horizontal plane of reference called the ground plane γ and a picture plane π... The line of intersection of π and γ is called the ground...

that if a finite, connected, planar graph is drawn in the plane without any edge intersections, and v is the number of vertices, e is the number of edges...

people on the ground. The plane, a Learjet 45, was carrying Mexican Secretary of the Interior Juan Camilo Mouriño. The plane crashed in rush-hour traffic...

Frankfurt-Mandibular plane Angle (FMA) is the angle formed at the intersection of the Frankfurt plane with the mandibular plane. In quadrupeds the standard...

generally introduced in terms of the geodesics and their intersections on the hyperbolic plane. Once we choose a coordinate chart (one of the "models")...

In mathematics, a cubic plane curve is a plane algebraic curve C defined by a cubic equation ⁠ F ( x , y , z ) = 0 {\displaystyle F(x,y,z)=0} ⁠ applied...
