Best ResponseYou've already chosen the best response.1(10.03 HC) Look at the figure shown below. A student made the table shown below to prove that XY is equal to YZ. Sample Response Statements Justifications 1. NY = MY Given 2. m∡MYX = m∡NYZ Given 3. m∡XNY = m∡ZMY Given 4. 5. m∡MYZ = m∡MYX + m∡XYZ Angle Addition Postulate 6. m∡MYZ = m∡NYZ + m∡XYZ Substitution 7. m∡NYX = m∡MYZ Transitive Property 8. XYN ≅ ZYM ASA postulate 9. 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.

Best ResponseYou've already chosen the best response.1What do we need to say first when you start adding angles to make 5. m∡MYZ = m∡MYX + m∡XYZ Angle Addition Postulate this valid?

Best ResponseYou've already chosen the best response.1When you start adding congruent angles, there's something you'd have to mention.

Best ResponseYou've already chosen the best response.1You'd need to mention that Angle XYZ = Angle XYZ by the reflexive property :)

Best ResponseYou've already chosen the best response.1Since when you substitute m∡NYZ in #5 5. m∡MYZ = m∡MYX + m∡XYZ 6. m∡MYZ = m∡NYZ + m∡XYZ You proved that MYX = NYZ, but not XYZ = XYZ, that what I meant by 'when you start adding congruent angles'.
