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
