83Fermat point — In geometry, the first Fermat point, or simply the Fermat point, also called Torricelli point, is the solution to the problem of finding a point F inside a triangle ABC such that the total distance from the three vertices to point F is the… …
84Dynamic programming — For the programming paradigm, see Dynamic programming language. In mathematics and computer science, dynamic programming is a method for solving complex problems by breaking them down into simpler subproblems. It is applicable to problems… …
85Pedal triangle — In geometry, a pedal triangle is obtained by projecting a point onto the sides of a triangle.More specifically, consider a triangle ABC , and a point P that is not one of the vertices A, B, C . Drop perpendiculars from P to the three sides of the …
86Centroid — of a triangle In geometry, the centroid, geometric center, or barycenter of a plane figure or two dimensional shape X is the intersection of all straight lines that divide X into two parts of equal moment about the line. Informally, it is the… …
87Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
88Desargues' theorem — Perspective triangles. Corresponding sides of the triangles, when extended, meet at points on a line called the axis of perspectivity. The lines which run through corresponding vertices on the triangles meet at a point called the center of… …
89Sperner's lemma — You may be looking for Sperner s theorem on set families In mathematics, Sperner s lemma is a combinatorial analog of the Brouwer fixed point theorem. Sperner s lemma states that every Sperner coloring of a triangulation of an n dimensional… …
90Median (geometry) — For another use of the term median in geometry, see Geometric median. The triangle medians and the centroid. In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposing side. Every triangle has exactly… …
