## Transformations and Dilations in the Coordinate Plane

Students will review the coordinate notation for transformations, including translation, reflection, and rotation as well as dilation. The TI-83 or TI-84 Plus Silver Edition graphing calculators are used to explore these transformations with familiar figures such as a broken heart (half a heart) and a flower petal or feather.
