Show that the vectors ` vec a , vec b` and` vec c` are coplanar if ` vec a+ vec b , vec b+ vec c` and ` vec c+ vec a` are coplanar.

Show that the vectors vec a,vec b,vec c are coplanar if and only if vec a+vec b,vec b+vec c and vec c+vec a are coplanar.

Show that vectors vec a,vec b,vec c are coplanar if vec a+vec b,vec b+vec c,vec c+vec a are coplanar.

The vectors vec a,vec b,vec c,vec d are coplanar then

If the three vectors vec a,vec b,vec c are coplanar, prove that the vectors vec a+vec b,vec b+vec c and vec c+vec a are also coplanar.

veca , vec b , vec c are non-coplanar vectors and x vec a + y vec b + z vec c = vec 0 then

Show that the vectors vec a-vec b, vec b-vec c, vec c-vec a are coplaner.

If vec a,vcb and vec c are non-coplanar vectors, then show that vec a+vec b,vec b+vec c and vec c+vec a are also non-coplanar

If vectors vec a , vec b ,a n d vec c are coplanar, show that | vec a vec b vec c vec adot vec a vec adot vec b vec adot vec c vec bdot vec a vec bdot vec b vec bdot vec c|=odot

If vec a, vec b, vec c are coplanar vectors, then | vec a, vec b, vec cvec b, vec c, vec avec b, vec a, vec b] | = vec a

If the vectors vec a, vec b, vec c are coplanar, then the value of | (vec a, vec b, vec c), (vec a * vec a, vec a * vec b, vec a * vec c), (vec b * vec a, vec b * vec b, vecb * vec c) | =
