 07-26-2007 #4 foofoo19472 Guest   Posts: n/a It means that they did not draw everything exactly the right size. If a map is drawn to scale, you can take a ruler out, measure things, and figure out how far away they are. If it's not drawn to scale, then it's just a picture showing how things are positioned relative to each other.The same thing is true in math. If it's drawn to scale, you can figure things out with a ruler and compass. If it's not drawn to scale, you have to use mathematical principles to calculate everything, based on whatever measurements might have been given.

Like if you see a square and it says its 8cm on all sides, but when you measure it with a ruler it actual 4cm on all sides, then you would call that not drawn to scale. Because that picture dosn't measure equal the same said measurement.
 07-26-2007 #6 T F Guest   Posts: n/a "Not drawn to scale" means that the proportions of figures in a picture are not necessarily accurate. For instance, if they show you two lines where one is supposed to be twice as long as the other in real life, a scale drawing would show one line that is twice as long as the other, like 2cm and 4cm lines representing 4 ft and 8 ft lines. If the picture were not drawn to scale, then 4 ft and 8ft lines might be represented by 2 cm and 3 cm lines, where the longer is not twice as big as the shorter.
