# Change the Dog: Transformations 4

Change the Dog: Transformations 4

Don Cohen, the Mathman, decided to write "Changing Shapes with Matrices" to share his interest and excitement about the ideas of changing shapes using matrices. The "dog" is taken from Don's book.

This Demonstration puts together all the transformations treated in the other "Change the Dog" Demonstrations. As you drag each group of sliders, ask yourself what happens when you change each number. In which direction does the dog move? Left, right, up, down, around in a circle? Perhaps it stretches!
