For the next lesson, we are going to go over translations. Remember: a translation is a congruence transformation where all of the points of an image are moved from one place to another place without changing. Another word for translations would be 'sliding'. The first image, the initial image, is called the pre-image, and then it goes to the new image. Translations are actually a composite of two reflections. Composite of reflections are two successive reflections over parallel lines. In this lesson you are going to learn how to find the translation image using a composite of reflections.
*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.
