Question

LMO=------------ by -------------

A.NOM,SAS
B.MOM,SSS
C.Nom,SSS
D.cannot be determined

Answer 1

We have LM=NO and LO=NM and by reflexivity MO=OM. So by SSS we have congruent triangles LMO=NOM. Note the careful ordering so the corresponding parts correspond.

By corresponding parts of congruent triangles, we have angle LMN = angle NOM.

Answer: C
