The congruence theorem that can be used to prove triangle LON is congruent to triangle LMN is

Answer: SSS
Step-by-step explanation:
In the given picture we have two triangles [tex]\triangle{LON}[/tex] and [tex]\triangle{LMN}[/tex] in which
[tex]\overline{LO}\cong\overline{LM}\ \ \ \text{[Given]}\\\\\overline{ON}\cong\overline{MN}\ \ \ \text{[Given]}\\\\\overline{LN}\cong\overlien{LN}\ \ \ \text{[Reflexive Property]}[/tex]
Thus by SSS congruence criteria we have,
[tex]\triangle{LON}\cong\triangle{LMN}[/tex]
