1. It is stated that ∆BAC ≅ ∆EAD. What makes this statement true? →SAS
2. Is ∆ABD ≅ ∆CBD?

→Yes, by SSS

3. Which of the following statements are true about ∠ABD and ∠CBD?

→They are right.

4. Why is ΔABD congruent to ΔACD?


5. How can we tell that ∠BAD is congruent to ∠ADB. Why?


6. Since ∠BAD ≅ ∠ADB, and m∠BAD + m∠ADB = 90, this means that:

→m∠BAD = 45

7. Which is true about AD?

→Both (A) and (B)

8. When is SSA enough information to conclusively prove that two triangles are congruent?→Only when another angle has been determined to be 90°
9. Is ∆ABC congruent to ∆EDC?


10. Which piece of given information would be enough to prove that ΔABC was congruent to ΔEDC?
