Introduction

Geometry is a branch of mathematics that deals with the study of shapes, sizes, and positions of objects in space. One of the fundamental concepts in geometry is the notion of collinear points. In this article, we will discuss the definition of collinear points, their properties, and some of the theorems associated with them.

Definition of Collinear Points

Collinear points refer to a set of three or more points that lie on a straight line. These points are said to be on the same line and are connected by a single path. The line on which the points lie is referred to as a collinear line.

Examples of Collinear Points

Let's consider three points A, B, and C. If A, B, and C are on the same line, then they are collinear points. For instance, the points A(1,2), B(2,4), and C(3,6) are collinear since they all lie on the line y=2x.

Properties of Collinear Points

Here are some of the properties of collinear points:

All the points lie on the same line.
Any two of the points can be used to determine the equation of the line passing through them.
Three non-collinear points define a unique plane, whereas three collinear points are always coplanar.

Theorems Associated with Collinear Points

Here are some of the theorems associated with collinear points:

The Midpoint Theorem

The midpoint theorem states that if AB is a line segment with midpoint M, then any point P on the line through A and B satisfies:

PA + PB = 2PM

Where PA denotes the distance between point P and point A.

The Triangle Inequality Theorem

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

The Angle Bisector Theorem

The angle bisector theorem states that if a point P lies on the interior of an angle formed by two rays with a common endpoint, then it divides the angle into two congruent angles.

Equation of Line	Any two points can be used to determine the equation of the line.	Three non-collinear points are needed to define a unique plane.
Geometric Properties	All points lie on the same line, and three points are coplanar.	Three points are not coplanar.

Conclusion

Collinear points are an essential concept in geometry with many properties and theorems associated with them.
