Proof of congruent geometry (I'm stuck!)

http://oi45.tinypic.com/24onfjm.jpg

Can someone solve this? Copy and Paste the link in your url bar, it doesn't show up plain.

1. given

2. WX ≅ YZ

3. ZX ≅ ZX

4. SSS postulate

5. ∠WZX ≅ ∠YXZ

1.Opposite side of rectangle.

2.WX = WY

3.ZX = ZX

4.SSS postulate.

5.Angle(WZX) = Angle(YXZ)

I don't understand what u should do :/
could u pls be more specific?
