Solution

step 1:- given:- following figures are given.

to find :- congruent triangles
step 2
:- $i n △ A C B a n d △ E F D A C = E F C B = F D A B = E D S O, △ A C B ≅ △ E F D (S S S)$
$i n △ R P Q a n d △ Z X Y R P = Z X P Q = X Y R Q = Z Y S O, △ R P Q ≅ △ Z X Y (S S S)$
$i n △ A C B a n d △ C A D A C = A C A B = C D B C = A D S O, △ A C B ≅ △ C A D (S S S)$
$i n △ P S R a n d △ P Q R P R = P R P S = P Q S R = Q R S O, △ P S R ≅ △ P Q R (S S S)$
