Answer:
(a). ∠A≅∠Z, ∠B≅X, ∠C≅∠Y
(b) Line AB≅ZX, Line AC≅ZY, Line BC≅XY
(c) ΔCBA≅YXZ
Explanation:
(a)
∠A≅∠Z because they both have two conguency lines
∠B≅X because they both have 3 congruencey liens
∠C≅∠Y because they both have one congruency line
(b)
Line AB≅ZX because they both have 1 congruency line
Line AC≅ZY because they both have 3 congruency lines
Line BC≅XY because they both have 2 conguency lines
I circled where the so called 'congruency lines' are so you know what i'm talking about in the screenschot attatched.
