Are triangles DEF and LNM similar if LN equals 4, MN equals 3, DE equals 12, and FE equals 9?
2 answers:
Answer:
A
Step-by-step explanation:
DE corrsponding to the LN, EF corrsponding to the MN, and LN:DE=MN:FE=3
and angel N is corrsponding to the angle E,so it 's SAS.
Answer:
Yes, by the SAS Similarity Postulate
Step-by-step explanation:
Here, DEF and LMN are two triangles,
In which,
LN = 4 unit,
MN = 3 unit,
DE = 12 unit,
FE = 9 unit,
Also, m∠DEF = m∠LMN = 90° ( given )
By the SAS similarity postulate ( two corresponding sides are in same proportion and corresponding included angles are equal )
FIRST option is correct.
