Supply the missing reasons and statements in the proof. Line xv intersecting line wy at point z

Statement Reason
LaTeX: \angle WZX\cong\angle WZV∠ W Z X ≅ ∠ W Z V Given
LaTeX: \angle WZX\:∠ W Z Xand LaTeX: \angle WZV\:∠ W Z Vare a linear pair.
[ Select ]
LaTeX: m\angle WZX+m\angle WZV=180m ∠ W Z X + m ∠ W Z V = 180
[ Select ]
[LaTeX: m\angle WZX=m\angle WZX=90m ∠ W Z X = m ∠ W Z X = 90] Supplementary congruent angles are right angles.
