Answer 2

Question:

In triangle ABC and triangle DEF, AB=DE, ∠A=∠D and AC=DF. Are  the triangles congruent? If yes , by which congruence rule?​

Given:

• AB = DE

• ∠A = ∠D

• AC = DF

To Prove:

Whether ΔABC ≅ ΔDEF or not

Solution:

Given In ΔABC and  ΔDEF

• AB = DE ( Given ) - Side

• ∠A = ∠D( Given ) - Angle

• AC = DF  ( Given ) - Side

By SAS Congruency criterion

ΔABC ≅ ΔDEF

Answer:

Yes the triangles are congruent By SAS Congruency criterion

ΔABC ≅ ΔDEF
