Question

ABCD is a quadrilateral in which AB= CD and AD=BC show that it is a parallelogram

Answer 1

Hey,
LOOK AT THE SIDE AB AND THEN THE CD SIDE.
THEN YOU WILL FIND THAT THE LENGTH OF SIDES BOTH AB AND CD ARE SAME AND THEY ARE ALSO PARALLEL TO EACH OTHER.
NOW LOOK AT THE SIDE AD AND THEN THE BC SIDE.
THE SAME CASE IS APPLIED. SO, A QUADRILATERAL IS SAID TO BE A PARALLELOGRAM, WHEN IT HAS TWO PAIRS OF OPPOSITE SIDES,ANGLES, ADJACENT SIDES,ANGLES ETC.
