Question

Part 3: Choose a proof method​

Answer 1

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

Hope it helps you mate

Answer 2

Answer: see proof below

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
