Transformation: The mapping, or movement, of all points of a figure in a plane according to a common operation, such as translation, reflection, rotation, or dilation

Lines of symmetry are examples of lines of reflection. Reflections are isometric, but do not preserve orientation. Translations are a slide or shift. Translations can be achieved by performing two …

Notice that translation is not a linear transformation, since translation does not satisfy Equation (8) on points; therefore translation cannot be represented by a 2 × 2 matrix.

ROTATION Translation, Rotation, and Reflection all change the position of a shape, while the size remains the same. The fourth transformation that we are going to discuss is called dilation.

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 …

• Optional – Markers or colored pencils (If your students are struggling with transformations, have them color code! It makes it easier!) This activity is great because you can have students complete it …
