True/false If one angle in a parallleogram is a right angled, then it is necessary a rectangle.

AB,CD are two parallel lines and a transversal l intersects AB at X and CD at Y Prove that the bisectors of the interior angles form a parallelogram,with all its angles right angles i.e.,it is a rectangle.

Prove that if one of the angles of a parallelogram be a right -angle , then it should be a rectangle.

Property 1each angle of a rectangle is a right angle.
