# Ch 27: Congruence and Similarity

Let us teach you about congruence and similarity, including the properties of congruence and similar shapes. These video lessons and quizzes will help you gain a solid understanding of solving problems using geometric patterns and properties.

## Congruence and Similarity - Chapter Summary

The video lessons in this chapter will show you about the properties of congruent and similar shapes. You'll learn to use the properties of congruence and similarity to explore geometric relationships, justify conjectures and prove theorems. Solving problems by using the properties of points, lines, planes, angles, lengths and distances are covered in these videos.

Another lesson uses geometric patterns and properties to make generalizations about two- and three-dimensional shapes, such as the relationships of sides and angles. You'll learn methods to determine if triangles are congruent. After watching all the videos in this chapter, you should have knowledge of these topics:

• Properties of dilations
• How to identify similar triangles
• Properties of congruent and similar shapes
• Similarity transformations
• Similar triangles and the AA Criterion
• Applications of similar triangles
• Proving similarity theorems about triangles
• Proving relationships in figures using congruence and similarity

You'll learn from experienced instructors who use examples from the real world to explain their points. Practice lessons allow you to hone your skills in problem solving. Every lesson contains a multiple-choice quiz so you can test your knowledge. The questions are linked back to the video, making it simple to review key passages and terms. The lessons are accompanied by a written transcript that also contains links to the video.
