it means that one cm is not necessarily 1 cm... just pretend it is....or it could say, look at this obtuse triangle when the triangle is obviously not obtuse...it's really suspending what you know and paying attention to what the problem is saying and not the picture.

It means that you can use the diagram only as a guide. You can not take measurements off the diagram because its only a sketch.

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.

It means that the diagram is not its actual real life size. 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.

"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.
