|Physical devices can be modeled using dynamic geometry. A vital tool for moving objects around in the model are the isometries, or distance-preserving transformations. This model of a Ferris wheel provides a good example. A step-by-step description of how to model a Ferris wheel using translations and animation in Sketchpad.|
