Lesson 4 Summary

 

This diagram shows a hammer being translated, reflected, dilated, and rotated.

In this lesson you looked at four ways of transforming an object.

  • A translation slides an object to a new position.
  • A reflection produces a mirror image of the original object.
  • A dilation changes the size of an object but not its shape.
  • A rotation turns a shape so as to change its orientation.

In the next lesson, you will explore how multiple transformations can be used successively.
