Answer 2

Step-by-step explanation:

If a parallelogram is known to have one right angle, then repeated use of co-interior angles proves that all its angles are right angles. If one angle of a parallelogram is a right angle, then it is a rectangle. ... A quadrilateral whose diagonals are equal and bisect each other is a rectangle.
