$\overrightarrow{AB}=\overrightarrow{BC}$  Implies B is the ....... of AB

Expand into single vector: $\overrightarrow{BJ}-\overrightarrow{LM}+\overrightarrow{JM}-\overrightarrow{BA}$  

 $\overrightarrow{AB}-\overrightarrow{CB}-\overrightarrow{DC}-\overrightarrow{ED}$  Write this as one vector

 $\overrightarrow{BA}+\overrightarrow{BC}=\overrightarrow{BD}$  Then D is the fourth vertex of a parallelogram :
