If ` vec a ,\ vec b` are the vectors forming consecutive sides of a regular of a regular hexagon `A B C D E F ,\ ` then the vecrtor representing side `C D` is
a.` vec a+ vec b` b. ` vec a- vec b` c. ` vec b- vec a` d. `-( vec a+ vec b)`

If vec a,vec b are the vectors forming consecutive sides of a regular of a regular hexagon ABCDEF, then the vecrtor representing side CD is vec a+vec b b.vec a-vec b c.vec b-vec a d.-(vec a+vec b)

[vec a, vec b + vec c, vec d] = [vec a, vec b, vec d] + [vec a, vec c, vec d]
