Collinearity is a property of mathematics exhibited by a set of co-ordinates in an area. Collinearity occurs in the plane. Three or more points P1, P2 and P3 are said to be collinear if they lie on a single straight line. Calculate collinearity of three points using this calculator.
Assessing collinearity will be meaningful only if we consider atleast three points, as a line between two points is always collinear. Any three points A(x1, y1), B(x2, y2) and C(x3, y3) are said to be collinear, if they satisfy the below condition.
(x1 - x2)/(x2 - x3) = (y1 -y2)/(y2 - y3)
x1 (y2 - y3) + x2 y3 - y1) + x3 (y1 - y2) = 0
In this Collinear Points Calculator, enter the values for points A, B and C and you would get the result if these points are collinear or not.
