 Collinearity equation

Collinearity refers to the condition where three or more points lie on the same straight line. In mathematics and geometry, collinearity can be determined using different methods, including the use of coordinates. For three points \(A(x_1, y_1)\), \(B(x_2, y_2)\), and \(C(x_3, y_3)\), one way to check if they are collinear is to use the area of the triangle formed by these points.
