Question

We now turn to examples and problems based on the criteria see
CONGRUEN
EXERCISE 7.2
1. Which congruence criterion do you use in the following?
A
(a) Given: AC = DF
AB=DE
B В
C С
BC = EF
So, AABC = ADEF
R
(b) Given: ZX = RP​

Answer 1

(a) Given : AC = DF

AB = DE

BC = EF

So, ∆ABC = ∆DEF

Since all three sides are equal, we use SSS congruency

(b) Given: ZX = RP

RQ = ZY

< PRQ = <XZY

So, ∆PQR = ∆XZY

Since two angles are between the same equal, we use SAS congruency.
