Consider the diagram shown Given MObar bisects angle LMN LMb
     Consider the diagram shown.  Given: MO^bar bisects angle LMN, LM^bar = MN^bar  Which statement explains whether there is enough information to classify angle MNO as a rhombus?  Yes, if a diagonal bisects one angle of a quadrilateral, then the opposite angle is also bisected.  Yes, if one pair of adjacent sides in a quadrilateral is congruent, then all four sides are congruent.  No, a pair of opposite angles would need to be congruent.  No, the diagonals would need to bisect each other. 
  
  Solution
LMNO can not yet be classified as a rhombus. Since we have yet not ensured that the point O is at the point where it should be for being a rhombus. To fix that we will need to add a property that the diagonals bisect each other.
Hence the correct option would be,
No, the diagonals need to bisect each other.
