## Collinear

### Points that lie on the same line

Collinear refers to a geometric concept where three or more points lie on a single straight line. Simply put, points that are collinear can be connected by a straight line. It is often represented using a mathematical notation, such as ABC indicating that points A, B, and C are collinear.

Collinear points can be found in different contexts, such as in geometry, engineering, and physics. For example, in geometry, collinear points are used to describe the position of objects in space and to analyze the properties of lines and angles. In engineering, collinear points are used to design and build structures, such as bridges and buildings, and to calculate the forces acting on them. In physics, collinear points are used to study the properties of particles and their interaction with other particles.

It is important to note that collinear points are not limited to just three points, as any number of points can be collinear if they lie on a single straight line. Thus, the concept of collinear points is crucial in various fields and is used in a wide range of applications.
