If three points are collinear, then they lie on a line. Let first calculate distance between the 3 points i. Thus, P, Q and R all collinear. Davneet Singh has done his B.

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. The term 'collinear' is derived from a Latin word where 'col' means 'together' and linear means 'line'. Thus, collinear, means the points lying together on a single line. Collinear points can be seen in our day-to-day lives, for example, the eggs placed in a row, or, the numbers printed on a ruler are collinear. As per the collinearity property, three or more than three points are said to be collinear when they all lie on a single line. The term collinearity has been used to indicate that the objects lie on a single line or in a row. Let us have a look at an example to understand collinearity better. If we plot these points in the cartesian plane, we find that they are collinear. When a line passes through three or more points, the points are said to be collinear points. In other words, the points lying on a straight line are called collinear points.

Show that the points are collinear

Collinear points are the points that lie on the same straight line or in a single line. If two or more than two points lie on a line close to or far from each other, then they are said to be collinear, in Euclidean geometry. Therefore, collinear points mean points together in a single line. You may see many real-life examples of collinearity such as a group of students standing in a straight line, a bunch of apples kept in a row, next to each other, etc. In geometry, two or more points are said to be collinear, if they lie on the same line.

Suppose the points A x 1 , y 1 , B x 2 , y 2 and C x 3 , y 3 are collinear, then the Conditions for Collinearity of Three Points are :. Join Teachoo Black. Maths Classes. Area Of Rectangle.

Properties Of Trapezium. In geometry, a point determines the location of a plane. Last updated at May 29, by Teachoo. Area Of Rectangle. We can find the collinearity with three points in different methods such as: i Using slope formula ii Using distance formula iii Using area of triangle formula iv Using equation method. The points A, B and C are collinear points if they lie on the same line in a plane. This can be proved using the distance formula in coordinate geometry. Example 4 Show that the points P —2, 3, 5 , Q 1, 2, 3 and R 7, 0, —1 are collinear. FREE Signup. Old search 1. Volume Of Cuboid. Geometric Shapes. That means, they can be collinear or noncollinear depending on the position of these points in a plane.
