In geometry, collinearity of a set of points is the property of their lying on a single line. A set of points with this property is said to be collinear (sometimes spelled as colinear ). In greater generality, the term has been used for aligned objects, that is, things being "in a line" or "in a row". See more In any geometry, the set of points on a line are said to be collinear. In Euclidean geometry this relation is intuitively visualized by points lying in a row on a "straight line". However, in most geometries … See more Two numbers m and n are not coprime—that is, they share a common factor other than 1—if and only if for a rectangle plotted on a square lattice with vertices at (0, 0), (m, 0), (m, n), (0, n), at least one interior point is collinear with (0, 0) and (m, n). See more Given a partial geometry P, where two points determine at most one line, a collinearity graph of P is a graph whose vertices are the points of P, where two vertices are See more In statistics, collinearity refers to a linear relationship between two explanatory variables. Two variables are perfectly collinear if there is an exact linear relationship between the two, so the correlation between them is equal to 1 or −1. That is, X1 and … See more Triangles In any triangle the following sets of points are collinear: • See more Collinearity of points whose coordinates are given In coordinate geometry, in n-dimensional space, a set of three or more distinct points are collinear if and only if, the matrix of the coordinates of these vectors is of rank 1 … See more In various plane geometries the notion of interchanging the roles of "points" and "lines" while preserving the relationship between them is called plane duality. Given a set of collinear points, by plane duality we obtain a set of lines all of which meet at a common … See more WebDec 4, 2015 · Sorted by: 2. Collinear means the three points are on the same line a x + b y + c = 0, that is. ( x 1 y 1 1 x 2 y 2 1 x 3 y 3 1) ( a b c) = 0.
