Congruence of Triangles | Exercise 7.2

Question 1

Q1) Which congruence criterion do you use in the following?

a) Given: AC=DF

AB=EF

BC=EF

So, \Delta ABC\cong\Delta DEF

b) Given: ZX=RP

RQ=ZY

\angle PRQ=\angle XZY

So, \Delta PQR\cong\Delta XYZ

c) Given: \angle MLN=\angle FGH

\angle NML=\angle GFH

ML=FG

d) EB=DB

AE=BC

\Delta ABE\cong\Delta CDB

Solution 1:

a) SSS congruence

b) SAS congruence

c) AAS congruence

d) SAS congruence
