To solve the worksheet, students should understand the following types of transformations:
Translation: The slide of an object without turns or flips; a translation preserves the size, shape, and orientation of the shape (congruent images).
Rotation: A turn around a center point; a rotation preserves the size and shape (congruent images), but not the orientation.
Reflection: A flip of the shape over a line (line of reflection) resulting in a mirror image; a reflection preserves the size and shape (congruent images), but not the orientation
Dilation: A transformation where a shape is made larger or smaller without any change in its position or orientation. The pre-image and the image will be similar shapes
