By developing the confidence and the skills to tackle geometry and measurements, you will not only improve your math skills with the four basic operations, but will also hopefully transfer your knowledge to other mathematical areas. A key feature of this unit is that you will be required to spend considerable amount of time looking at various isometries. Through this exposure to isometries, not only are you going to be more knowledgeable about these transformations and understand the main facts about them, but will also hopefully transfer your knowledge to other mathematical areas.

The relationship between reflection and rotation, and the relationship between reflection and translation are all explored through problem solving. By making connections between reflections, rotations, and translations, related word problems and examining different ways to look at rotations in terms of reflections, you should develop a better understanding of the relationships between the four types of isometries.

In some transformations, the figure retains its size and only its position is changed. The point a figure turns around is called the center of rotation.
