About This Chapter
Graphical Transformations - Chapter Summary
The short video lessons in this chapter offer a fun look at graphical transformations. Our instructors present the lessons in an entertaining manner that helps you get the gist of transformations, reflections, dilation, rotation and much more. Learn important definitions and explore examples that bolster your understanding. Check your knowledge by taking lesson quizzes and a chapter exam. In no time, you will be able to:
- Define and graph transformations in math
- Explain how reflection, rotation and translation work
- Summarize reflections in math
- Discuss rotations in math
- Share the meaning of dilation in math
- Graph reflections across axes, the origin and the line y=x
1. Transformations in Math: Definition & Graph
In geometry, transformation refers to the movement of objects in the coordinate plane. This lesson will define and give examples of each of the four common transformations and end with a quiz to make sure you are moving in the right direction.
2. 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.
3. Reflections in Math: Definition & Overview
A reflection of an object is a 'flip' of that object across a line. This lesson will describe the basics of reflection, how to recognize one and how to create one.
4. Rotations in Math: Definition & Overview
A geometric rotation refers to the rotating of a figure around a center of rotation. This lesson will get you going on rotations, give you some examples, and end with a quiz that tests your knowledge of rotations.
5. Dilation in Math: Definition & Meaning
Dilations are transformations that change figures in specific ways. Learn about these changes and how to complete dilations here. 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.
