If you don't tell us what the statements are, we can't tell you which ones could be false. The ones that could be false are the ones that state something that doesn't apply to congruent triangles.
To prove that ( OL \cong ON ), Nina can use the properties of isosceles triangles. Given that ( \angle OLN \cong \angle LNO ) and ( \triangle OLN ) has these equal angles, by the Isosceles Triangle Theorem, the sides opposite those angles must be congruent. Therefore, ( OL \cong ON ) follows from the fact that the angles are congruent.
Vietnam could be considered as being synonymous to Viet Cong.
