What does it mean when you see the phrase “Not Drawn to Scale” next to a geometric image? What might happen if you use a measurement tool to solve this type of problem? When an image in not drawn to scale what is the best strategy one can use to solve the problem?
When you see the phrase, "Not Drawn to Scale" next to a geometric image, it means you won't get the answer if you solve using a measurement tool. If you use a measurement tool to solve the problem like a ruler for instance, the amount on the ruler will not equal the amount on the grid. When an image is in a grid that says not drawn to scale, the best strategy to use is perimeter or area. They focus on the figure size in the coordinate plane so there is no need to use a ruler or another measurement tool.
ReplyDeleteDaniel, I love that you used examples to demonstrate your understanding! Are perimeter and area the only types of problems where you would see images that are not drawn to scale?
