Question

EXERCISE 7.2
Q 1 Which congruence criterion do you use in the following?
A) Given: AC =DF
AB = DE
BC = EF
So, AABC = ADEF​

Answer 1

Answer:

SSS Congruence criterion

Step-by-step explanation:

Given instruction shows all about sides.

So, we will use SSS Congruence criterion.

Answer 2

Answer

Answer:

By SSS congruence criterion, 

since it is given that

 AC=DF, 

AB=DE,

 BC=EF.

 The three sides of one triangle are equal to the three corresponding sides of another triangle.

Therefore,

 ΔABC≅ΔDEF.
