This activity allows the user to measure angles and explore the concept of "scale" as it pertains to maps, images, and drawings. The scale feature allows the user to define a scale and then using that scale, measure distances or areas on a selected image. Understanding scale measurements requires understanding the concept of proportion. When using a scale model or drawing, a ratio is given such that a measurement taken from the model or drawing represents another measurement, presumably the "life size" measurement the model or drawing represents. This ratio can then be set equal to a second ratio where a second measurement is taken from the model or drawing in order to determine the unknown "life size" measurement.
