Chapter 3.3, Problem 3EYU

Several vectors are shown in Figure 3-16. The red vectors have a magnitude equal to a diagonal across the square formed by the blue vectors. Which of the given vectors represents the following quantities: (a) $\stackrel{\to }{\text{A}}\text{+}\stackrel{\to }{\text{B}}$, (b) $\stackrel{\to }{\text{D}}\text{-}\stackrel{\to }{\text{A}}$, (c) $\stackrel{\to }{\text{G}}\text{-}\stackrel{\to }{\text{C}}$, and (d) $\stackrel{\to }{\text{B}}\text{+}\stackrel{\to }{\text{H}}\text{-}\stackrel{\to }{\text{D}}$?
