Picturing, both on paper and in your mind, is an important part of geometric reasoning. You can learn the mathematics of making accurate drawings, drawings from which you can reason. You can also learn to pay more attention to the geometry you see and to visualize with your mind.
In the following Interactive Activity, you'll stretch both your visualization and drawing muscles. You'll see an image briefly and then try to draw it from memory on a piece of paper. Note 2
This activity requires the Flash plug-in, which you can download for free from Macromedia's Web site. If you prefer, you can view the non-interactive version of this activity, which doesn't require the Flash plug-in.
