# Ch 21: Advanced Middle School Geometry

This convenient study resource covers advanced geometry concepts for middle school grade levels. These short and engaging lessons instruct on geometric proofs, theorems, formulas and graphing concepts.

## Advanced Middle School Geometry - Chapter Summary

This advanced middle school geometry chapter covers important geometric proofs, formulas and theorems that are commonly taught at the middle-school level. These lessons go over concepts such as congruence and similarity and define terms like reflection, rotation and translation. You'll practice graphing transformation and see how to properly format geometric proofs. These lessons help you use the Pythagorean theorem to find distance and plot figures on a coordinate graph. After going through each lesson in the chapter, you should be able to:

• Understand congruence and similarity in geometric shapes
• Define reflection, rotation and translation
• Plot simple figures on coordinate graphs
• Find distance using the Pythagorean theorem
• Graph transformations
• Know the formula for finding scale factors
• Assess trigonometric ratios and similarity
• Format geometric proofs

The lessons in this chapter are typically less than 10 minutes in length, which helps you quickly review essential geometry concepts in bite-sized chunks. Our expert instructors use straightforward definitions and support them with practice problems and examples so you can easily remember them. After you finish a lesson, you can make sure you fully understand what you've covered by taking the accompanying self-assessment quiz. You can access the chapter material at any time and on any computer or mobile device, which makes the learning process flexible and convenient.
