Question

Will give medal and fan.
Look at the figure shown below.
A student made the table shown below to prove that XY is equal to YZ.
Statements Justifications
NY = MY Given
m∡MYX = m∡NYZ Given
m∡XNY = m∡ZMY Given
Missing Proof.
m∡MYZ = m∡MYX + m∡XYZ Angle Addition Postulate
m∡MYZ = m∡NYZ + m∡XYZ Substitution
m∡NYX = m∡MYZ Transitive Property
triangleXYN ≅ triangleZYM ASA postulate
XY = ZY CPCTC
A. Provide the missing statement and justification in the proof.
B. Using complete sentences, explain why the proof would not work without the missing step.
