Tell which congruence postulate or theorem you would use to show that thetriangles are congruent.

From the given figure, we know that:
[tex]\begin{gathered} NO\cong LO \\ NM\cong LM \\ MO\cong MO \end{gathered}[/tex]This means that the three sides of triangle MNO are congruent to three sides of triangle LMO. Therefore, the triangles are congruent by Side Side Side postulate.
