Write a two column proof. Given: MN is congruent to PN and LM is congruent to LP. Prove: MLN is congruent to PLN

Answer:
Given :
In triangles MLN and PLN,
MN ≅ PN,
LM ≅ LP
To prove :
Δ MLN ≅ Δ PLN
Proof :
Statement Reason
1. LN ≅ LN 1. Common segment
2. MN ≅ PN; 2. Given
LM ≅ LP
3. Δ MLN ≅ Δ PLN 3. SSS postulate of congruence,
Hence, proved.
