Understanding Similarity Transformations

This lesson covers similarity transformations, focusing on the properties of similar figures. It explains how similarity differs from congruence, emphasizing the importance of corresponding angles and proportional side lengths. The lesson includes practical applications, such as solving problems using ratios and proportions, and concludes with a review and practice recommendations.

What is the main focus of Lesson 17-3?
