If BCDE ≅ OPQR, then DE =

∠ABC≅ ? (a)  

• ∠PMN
• ∠NPM
• ∠NMP
• ∠MNP

The two triangles are congruent. Find the value of c.

(Diagrams are not to scale.)

Given: ∆ABC≅∆PQR, m∠B=3V+4, & m∠Q=8v-6. Find m∠B

[Hint: DRAW A PICTURE!]

Complete the Reason for Step 4. in the proof.

What other information do you need in order to prove the triangles congruent using the SAS Congruence Postulate?

State whether ∆ABC and ∆AED are congruent. Justify your answer.

• yes, by either SSS or SAS

• yes, by SSS only

• yes, by SAS only

• Not enough information to reach a conclusion.

• No, they are NOT congruent
