- When two or more points lie on the same line, they are called collinear points.
- Yes, we can draw a straight line through collinear points.
- When the points in a place, does not lie on the same line, then such points are called non-collinear points.
- There are three methods to find if the points are collinear, they are: Distance formula Slope formula Area of triangle
- True, if three points are collinear then slope of points formed by these points are equal.
- Slope Formula
- Area of Triangle Formula
- Distance Formula
We apply the slope formula to find the slope of lines formed by the 3 points under consideration. If the 3 slopes are equal, then the three points are collinear. For example, if we have three points X, Y, and Z, the points will be collinear only if the slope of line XY = slope of line YZ = slope of line XZ. To calculate the slope of the line joinin...
In this method, we use the fact that a triangle cannot be formed by three collinear points. This means if any 3 points are collinear they cannot form a triangle. Therefore, we check the points of the triangle by using them in the formula for the area of a triangle. If the areais equal to 0, then those points will be considered to be collinear. In o...
Using the distance formula, we find the distance between the first and the second point, and then the distance between the second and the third point. After this, we check if the sum of these two distances is equal to the distance between the first and the third point. This will only be possible if the three points are collinear points. To calculat...
Illustrated definition of Collinear: When three or more points lie on a straight line. (Two points are always in a line.)

Jun 18, 2024 · Three or more points P_1, P_2, P_3, ..., are said to be collinear if they lie on a single straight line L. A line on which points lie, especially if it is related to a geometric figure such as a triangle, is sometimes called an axis.
In Geometry, a set of points are said to be collinear if they all lie on a single line. Because there is a line between any two points, every pair of points is collinear. Demonstrating that certain points are collinear is a particularly common problem in olympiads, owing to the vast number of proof methods.
