Answer:
The third step is missing and it is
3. Angle WZX = angle YZX
The reasons for step 3,4 and 5 are
3. Each measure angle equal to 90°
4. Right - Hypotenuse - Side Test
5. Congruent parts of congruent triangles.
Step-by-step explanation:
In Δ WXZ and Δ YXZ
[tex]WX = YX \ \textrm{given}\\XX = XZ \ \textrm{reflexive property of congruence}\\\angle WZX = \angle YZX\ \textrm{measure of each angle is 90°}\\\triangle WXZ = \triangle YXZ\ \textrm{Right Hypotenuse Side Tests}\\WZ = ZY\ \textrm{Corresponding parts of congruent triangles}\\[/tex]
Hence proved.
