5/5 Lesson 6.2.2 Dilations and Similar Figures

1.  Warm-up:  Solving and Graphing Inequalities (on side whiteboard)

2.  Lesson 6.2.2 Dilations and Similar Figures

Key Concepts:

• Congruent vs. Similar
• Rigid transformations vs. Dilations
• How to undo a dilation

Problem 52 using eTool

Problem 53 using eTool.  This problem is a little confusing.  The coordinates given are AFTER she dilates the original shape by a scale factor of ¹/₃ 

Discuss the questions in Problem 54 (no need to write).  CPM is expecting you to start making connections about dilations.

Problems 55 through 57 are the most important.

• Take your time. Make predictions and discuss them with your team.  Then, test the predictions using the eTool
