Question

State crosspondens between the angle and side if triangle ABC is congruent to triangle A P Q

​

Answer 1

Hii
congruent:   AB = DE          BC = EF          CA = FD         

Corresponding angles are congruent: ∠A = ∠D          ∠B = ∠E          ∠C = ∠F          

In the congruent triangles we will observe six correspondences between their verities. The symbol used to denote correspondence is ‘↔’

A ↔ D             B ↔ E              C ↔ F              written as ABC ↔ DEF

A ↔ E             B ↔ F              C ↔ D              written as ABC ↔ EFD

A ↔ F             B ↔ D              C ↔ E              written as ABC ↔ FDE

A ↔ D             B ↔ F              C ↔ E              written as ABC ↔ DFE

A ↔ E             B ↔ D              C ↔ F              written as ABC ↔ EDF

A ↔ F             B ↔ E              C ↔ D              written as ABC ↔ FED

Therefore, ∆ABC ≅ ∆DEF
