How can the triangles be proven similar by the sss similarity theorem?

show that the ratios startfraction u v over x y endfraction , startfraction w u over z x endfraction , and startfraction w v over z y endfraction are equivalent.
show that the ratios startfraction u v over z y endfraction , startfraction w u over z x endfraction , and startfraction w v over x y endfraction are equivalent.
show that the ratios startfraction u v over x y endfraction and startfraction w v over z y endfraction are equivalent, and ∠v ≅ ∠y.
show that the ratios startfraction u v over z y endfraction and startfraction w u over z x endfraction are equivalent, and ∠u ≅ ∠z.
