| style="height:20px; width:200px; text-align:center;" |The [[vector]] <math>\underline{b}</math> is shown by this arrow. The length of the arrow represents the [[magnitude]] of the [[vector]] and the direction of the arrow shows the direction of the [[vector]].

|style="height:100px; width:400px; text-align:left;" colspan = '"2'"|The arrow <math>\underline{b}</math> is shorter than the arrow <math>\underline{a}</math> so the [[vector]] <math>\underline{b}</math> has a smaller [[magnitude]] than <math>\underline{a}</math>. It can also be seen that [[vector]] <math>\underline{b}</math> has a different direction to [[vector]] <math>\underline{a}</math>.

: Using a [[diagram]] two [[vector]] quantities can be added together by drawing the arrows end to end.
<math>\underline{a}+\underline{b}=\underline{c}</math>

|style="height:100px; width:400px; text-align:left;" colspan = '"2'"|If the [[vector]]s are drawn [[accuracy|accurately]] and [[precision|precisely]] in [[length]] using a [[ruler]] and in direction using a [[protractor]] the [[length]] and direction of the new [[vector]] can be [[measure]]d from the [[diagram]]. This type of [[Scale Diagram]] can be used to find the [[magnitude]] and direction of the new [[vector]] without calculation.
