A:

begin mathsize 16px style PQ equals RS space and space PN space parallel to QM
rightwards double arrow angle RPN equals angle SQM
And comma space PR equals QS
RN parallel to SM
rightwards double arrow angle PRN equals angle QSM
Then comma space increment PRN approximately equal to increment QSM space space space space left parenthesis by space ASA space congruency right parenthesis
rightwards double arrow PN equals QM space and space RN equals SM space space space space space space left square bracket cpct right square bracket
Since space PN space parallel to QM space and space PN equals QM comma space PQMN space is space straight a space parallelogram.
Similarly comma space RN parallel to SM space and space RN equals SM comma space RSMN space is space straight a space parallelogram.
Thus comma space PQ equals MN space and space PQ parallel to MN end style
