Three points A,B,C are collinear they lie on the shown in the figure.can you draw `triangleABC`?if not why .

Collinearity of three points

Take three collinear point A,B and C on a page of your note book.Join AB,BC and CA is the figure a triangle? If not,why?

Three blocked A,B and C are placed one over the other as shown in figure. Draw free body diagram of all the three blocks.

Given four points A, B, C, D such that three points ABC are collinear. By joining these points in order to get a closed figure, we get :-

Show that the three points (3,0),(-2,-2) and (8,2) are collinear. Also, find the equation of the straight line on which these points lie.

If O be the origin the vector vec(OP) is called the position vector of point P. Also vec(AB)=vec(OB)-vec(OA) . Three points are said to be collinear if they lie on the same stasighat line.Points A,B,C are collinear if one of them divides the line segment joining the others two in some ratio. Also points A,B,C are collinear if and only if vec(AB)xxvec(AC)=vec0 Let the points A,B, and C having position vectors veca,vecb and vecc be collinear Now answer the following queston: (A) veca.vecb=veca.vecc (B) vecaxxvecb=vecc (C) vecaxxvecb+vecbxxvecc+veccxxveca=vec0 (D) none of these

If the points A (x,y), B (1,4) and C (-2,5) are collinear, then shown that x + 3y = 13.

Through three collinear points a circle can be draw.
