Part 3: Choose a proof method

Answer: see proof below
Step-by-step explanation:
Statement Reason
1. ∠WZX ≅ ∠YZX 1. Given
2. ZW ≅ ZY 2. Given
3. ZX = ZX 3. Reflexive Property
4. ΔWZX ≅ ΔYZX 4. SAS Congruency Theorem
5. WX = YX 5. CPCTC
6. ∠WXZ = 90° 6. bisector of isosceles ΔWZY
∠YXZ = 90°
7. ZX is perpendicular bisector of WY 7. Definition of perpendicular bisector
Step-by-step explanation:
In this question we have to prove that zx = wy
the question is proved in the above attachment
and as we know that the straight line is of 180 degree and Ab is the bisector of line so the angles are also equally divided it means angle zxw= 90 and zxy = 90
