## Introduction

Today we will explore what the “ingredients” of a rotation are and the properties that a rotation changes and not change?
- Make sure that your triangle has the following coordinates: A(-5, 4), B(-2, 5), & C(-1, 2)
- Make sure that the box that says "Show Image" is clicked.
- Make sure that the box that says "Show Movement of Points" is clicked.
