Answer:
LMNO is a parallelogram
Explanation:
In the two Δ NML and LON
∵ NM = LO ⇒ given
∵ ML = ON ⇒ given
∵ NL is a common side
∴ ΔNML ≅ ΔLON ⇒(SSS)
∴ m∠MLN = m∠ONL ⇒ in alternate position
∴ LM // ON
∵ LM = ON
∵ LM and ON are two opposite sides in quadrilateral LMNO,
they are equal and parallel
∴ LMNO is a parallelogram
