To show three vectors are coplanar,first find out the cross product of any two vectors and then find the dot product of the resaultant vector and the third vector,if the dot product is zero then the given three vectors are coplanar.

Just for explanation,the cross product is actually perpendicular to the plane containing the first two vectors, and hence the third vector if coplanar to the first two vectors, hence will be perpendicular to the cross product vector.
