Lesson 10. Unit 3. Grade 8 EngageNY


This Problem Set is a part of the Lesson 10, Unit 3, Grade 8. Students know an informal proof of the angle-angle (AA) criterion for similar triangles. Students present informal arguments as to whether or not triangles are similar based on the AA criterion. Recall the exercise we did using lined paper to verify experimentally the properties of the fundamental theorem of similarity (FTS).
