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 …
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.
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
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.
acher Notes If you want to make a class set, I would recommend laminating the cheat sheet so that you can use it year. after year. You could also decide to print a cheat sheet for each …
In this unit, some transformations will be done within the coordinate plane, and others will be done without reference to any coordinate system. These examples will be intermixed, as the …
