points are colline
Ex. 4) Show that the following points ar
by determinant method.
A(2, 5), B(5, 7), C(8,9)​

Answer 1

Answer:

Step-by-step explanation:

The points are A(a,b+c), B(b,c+a), C(c,a+b). If the area of triangle is zero then the points are called collinear points. If three points (x , y ), (x , y ) and (x , y ) are collinear then [x (y - y ) + x ( y - y )+ x (y - y )] = 0. ... ∴ the points (a,b+c), (b,c+a), (c,a+b) are collinear.Oc
