Question

Look at attatched figure:
A student made the table shown below to prove that MN is equal to NT.
Statements Justifications
1. RN = PN Given
2. m∡PNM = m∡RNT 1. Given
3. m∡MRN = m∡TPN 2. Given
4. m∡PNT = m∡PNM + m∡MNT 4. Angle Addition Postulate
5. m∡RNM = m∡RNT + m∡MNT 5. Angle Addition Postulate
6. 6. ?
7. m∡PNT = m∡RNM 7. Transitive Property
8. RNM ≅ PNT
8. ASA postulate
9. MN = TN 9. 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.

Answer 1

m∡MYZ = m∡NYZ + m∡XYZ by substitution i have the same question just that the blank was in #4 jaja :p

Answer 2

line 6 angle MNT = angle MNT by Reflexive proprty

Answer 3

and why wouldnt it work?

Answer 4

you need that step to fit the second pair of angles needed in Angle-Side-Aangle

Answer 5

K. again, thank you:)

Answer 6

yw...:)

Answer 7

read that countrygurl96 so you can see the answer

Answer 8

thnx
