Question

Exercise - 4
Which congruence criterion do you use in the following?
(1)
Given : AC=DF
AB=DE
BC= EF
C с
E
B
So, AABC = ADEF​

Answer 1

Answer:

By SSS congruence rule

Answer 2

BY SSS congruence criterion

since it is given that

AC = DF

AB = DE

BC = DF

The three sides of one triangle

are equal to three corresponding sides of another triangle

∆ ABC = DEF .
