### About This Chapter

## 6th-8th Grade Geometry: Transformations - Chapter Summary

The fun video lessons in the Transformations chapter allow you to teach the rules of transformations to your 6th - 8th grade students. Explain the process of graphing reflections, rotations and translations, and demonstrate the steps for determining the coordinates. Upon completing these video lessons, you could administer the chapter examination to ensure your students' grasp of math transformations.

## Chapter Lessons and Objectives

Lesson | Objective |
---|---|

Reflection, Rotation & Translation | Students are taught to identify transformations such as rotations, translations and reflections. |

Reflecting Simple Shapes in a Mirror Line | Teachers explain the steps for reflecting simple shapes in a mirror line. |

Line and Rotational Symmetries of 2-D Shapes | This lesson covers line and rotational symmetries of 2-D shapes. |

Graphing Translations & Finding a Set of Coordinates | The rules for finding coordinates and graphing translations are provided in this lesson. |

Rotating Shapes by Degrees, Center & Direction | Students learn how to rotate shapes by direction, center and degrees. |

How to Graph Reflections Across Axes, the Origin and Line Y=X | Instructors demonstrate how to draw mathematical reflections. |

Graphing Rotations & Finding Coordinates | In this lesson, instructors teach students to find coordinates and graph rotations. |

### 1. Reflection, Rotation & Translation

This lesson will define reflection, rotation, and translation as they relate to math. It will also show you an example of each one so that you can perform these transformations on your own.

### 2. Reflecting Simple Shapes in a Mirror Line

What is reflection? How can we reflect a shape over a line? You will learn about this as well as about the important properties of reflection as it relates to math!

### 3. Line and Rotational Symmetries of 2-D Shapes

One of the most important concepts in geometry is the idea of symmetry. But what does it actually mean? This lesson explains the difference between line symmetry and rotational symmetry.

### 4. Graphing Translations & Finding a Set of Coordinates

In this lesson, you're going to learn how to translate figures by counting boxes, find the coordinates of points, and learn how to translate a figure more quickly using simple math.

### 5. Rotating Shapes by Degrees, Center & Direction

In this lesson, you're going to learn about the definition and basic concept of rotation as well as how to rotate any shape about the origin in a coordinate plane. Finish up the lesson, then test your understanding with a quiz!

### 6. How to Graph Reflections Across Axes, the Origin, and Line Y=X

A graph can be reflected in three ways - across the axes, the origin and the line y = x. There are specific rules to perform each reflection. This lesson will describe those rules and show you how to perform these reflections.
