Question

In following pairs of triangles, find the pairs which are congruent? Also, write the criterion
of congruence​

Answer 1

Answer:

In ΔABC  

AB

=6.5cm

                 ∠B=70  

o

 

                 ∠C=60  

o

 

In ΔPQR  

RP

=6.5cm

                 ∠P=70  

o

 

                 ∠Q=60  

o

 

∴  

AB

≅  

RP

;∠B≅∠P;∠C≅∠Q

Line  

AB

 is congurent to  

RP

∴ΔABC≅ΔPQR SAA congurency i. e. ; ASA congurency.

Criterion :- SSS - congurency                      [Here S = side , A = Angle]

                  SAS - congurency  

                  ASA - conurency  

                  AAS - congurency
