  1. Chapter 6.4 Notes: Prove Triangles Similar by AA Goal: You will use the AA Similarity Postulate.

  2. AA Similarity (AA ~) Two triangles are similar if two of their corresponding angles are congruent.

  3. Ex.1: Determine whether the triangles are similar. If they are, write a similarity statement. Explain your reasoning.

  4. Ex.2: Show that the two triangles are similar. a. ∆ABE and ∆ACD b. ∆SVR and ∆UVT

  5. Ex.3: Show that the triangles are similar. Write a similarity statement. a. ∆FGH and ∆RQS b. ∆CDF and ∆DEF

  6. Ex.4:

  7. Ex.5: A school building casts a shadow that is 26 feet long. At the same time a student standing nearby, who is 71 inches tall, casts a shadow that is 48 inches long. How tall is the building to the nearest foot?
