1. If ∆ ABC = ∆ PQR, then ∠A corresponds to

2. If ∆ ABC = ∆ PQR, then ∠B corresponds to

3. If ∆ ABC= ∆ PQR, then ∠C corresponds to

4. We want to show that ∆ ART = ∆ PEN and we have to use SSS criterion. We have AR = PE and RT = EN. What more we need to show?

5. We want to show that ∆ ART = ∆ PEN. We have to use SAS criterion. We have ∠T = ∠N, RT = EN. What more we need to show?

6. We want to show that ∆ ART = ∆ PEN. We have to use ASA criterion. We have AT = PN, ∠A = ∠P. What more we need to show?

7. Which congruence criterion do you use in the following?

Given AC = DF
AB = DE
BC = EF
So, ∆ ABC ≅ ∆ DEF

8. Which congruence criterion do you use in the following?

Given : ZX = RP
RQ = ZY
∠ PRQ = ∠ XZY
So, ∆ PRQ = ∆ XYZ
