# Chapter 12: Rigid Transformations

**Basic**Created by: CK-12

## Introduction

The final chapter of Geometry transforms a figure by moving, flipping, or rotating it. First, we will look at symmetry, followed by the different transformations.

### Chapter Summary

## Summary

This chapter discusses transformations of figures in the two-dimensional space. It begins with an explanation of reflection and rotation symmetry. The chapter then branches out to discuss the different types of transformations: translation (sliding a figure to a new position), rotation (rotating a figure with respect to an axis), and reflection (flipping a figure along a line of symmetry). Now that the different types of basic transformations are discussed, the composition of these actions to create a new type of transformation is explored. The chapter wraps up with a detailed presentation of tessellations and regular polygons.
