For the next lesson, we are going to go over mappings. Mappings are transformations of a pre-image to another congruent or similar image. When you have an image, and it has either a congruent or a similar relationship with another image, then that is transformations, which is also mappings. The different types of transformations are rotation, translation, reflection, and dilation - four types of transformations. You'll learn about each of these types in this lesson. You'll also see some examples of each and learn about congruent transformations. In a plane, an isometry is a transformation that maps every segment to a congruent segment.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
