Collinear: Points are those points that lie on

Collinear points are those points that lie on the same straight line. It is not necessary that they should be co-planar but they must lie on the same straight line. Learn all about collinear points in geometry with simple definitions, real-life examples, and step-by-step methods to prove collinearity using slope, area, and vectors. Perfect for students and math enthusiasts. As per collinearity property, three or more than three points are said to be collinear when they all lie on a single line. As per the Euclidean geometry, a set of points are considered to be collinear, if they all lie in the same line, irrespective of whether they are far apart, close together, form a ray, a line, or a line segment. Collinearity is the property of points lying on a single line. Learn about collinear points in geometry, especially in triangles, quadrilaterals, and hexagons, and how to identify them using Menelaus' theorem, Pascal's theorem, and other criteria.
