Three points with position vectors, b and c are said to be colinear. If the parallelogram with adjacent sides a - b and a - c has zero geometry area. Use this fact to check whether or not the following triples of points are collinear
(a) (2,2,3), (6,1,5) (2,4,3)
(b) (2,3,3), (3,7,5), (0,-5,-1)
(c) (1,3,2), (4,2,1), (1,0,2)
(a)
Three points are not collinear.
(b)
Three points are collinear.
(c)
Three points are not collinear.
