Applying Properties of Congruence Triangle

ΔABC and ΔPQR are congruent under the correspondence ABC ↔RQP Write the parts of ΔABC that correspond to RQ.

• AB

• BC

• AC

• Non of these

Which angle is included between the sides DE and EF of ΔDEF?

• ∠D

• ∠E

• ∠F

• none of these

By applying SAS congruence rule, you want to establish that ΔPQR ≅ ΔFED. It is given

that PQ = FE and RP = DF. What additional information is needed to establish the

congruence?

• ∠P = ∠D

• ∠Q = ∠D

• ∠P = ∠F

• ∠R = ∠F

Which congruence criterion do you use in the following?

Given: AC = DF, AB = DE, BC = EF. So, ΔABC ≅ ΔDEF

• ASA rule

• SAS rule

• RHS rule

• SSS rule

ΔABC and ΔPQR are congruent under the correspondence ABC ↔RQP. Write the parts of ΔABC that correspond to PQ.

• CB

• AB

• AC

• none of these

Which congruence criterion do you use in the following?

Given: ZX = RP, RQ = ZY, ∠PRQ = ∠XZY. So, ΔPQR ≅ ΔXYZ

• ASA rule

• SSS rule

• RHS rule

• SAS rule
