TRANSLATIONS: Translations are a slide or shift. Translations can be achieved by performing two composite reflections over parallel lines. Translations are isometric, and preserve orientation. Coordinate plane rules: (x, y) (x ± h, y ± k) where h and k are the horizontal and vertical shifts.
REFLECTION Sometimes, a figure has reflectional symmetry. This means that it can be folded along a line of reflection within itself so that the two halves of the figure match exactly, point by point. Basically, if you can fold a shape in half and it matches up exactly, it has reflectional symmetry.
Use the rule you wrote in part (a) to translate ABC 4 units left and 3 units down. What are the coordinates of the vertices of the image, A ′ B ′ C ′? c. Draw A ′ B ′ C ′.

A translation is taking a figure and sliding the figure to a new location. A dilation is enlarging or reducing an image by a scale factor k. Rules Rules
This product involves four pages of interactive notes on translations, dilations, rotations and reflections. Each note page provides an opportunity for students to complete the definition, examine and compare the angles and sides of the images, list the pre-image and image coordinates and to describe in words the transformation completed.

In geometry, a transformation is a process by which a set of points is transformed, or changed. These changes can involve location, size, or both. We will be studying the following transformations: 1. Reflections 2. Translations 3. Rotations 4. Dilations Transformations are sometimes called mappings. We will refer to the initial set of points
