  1. Triangle Congruence by ASA and AAS Students will recognize the significance of elements in a triangle, such as the congruence of sides and angles, and will determine the congruence (or lack thereof) between two triangles using ASA and AAS.

  2. 4-3 Quiz • The following questions are to help you see how well you understood today’s lesson. • Please follow up with me if you don’t understand what you miss. • Record the number you got right on your portfolio sheet!

  3. 1. In each pair of triangles, parts are congruent as marked. Which pair of triangles is congruent by ASA?

  4. 2. What is the missing reason in the two-column proof? • ASA Postulate • SSS Postulate • SAS Postulate • AAS Theorem

  5. 3. From the information in the diagram, can you prove ∆FDG  ∆FDE? Explain. • Yes, by SAS • Yes, by AAA • Yes, by ASA • No

  6. 4. Can you use the ASA Postulate, the AAS Theorem, or both to prove the triangles congruent? • Neither • ASA • AAS • Either ASA or AAS

  7. 5. If A  D and C  F , which additional statement does NOT allow you to conclude that ∆ABC  ∆DEF?
