Question

the diagonals of a quadrilateral must bisect each other and be perpendicular to guarantee that the quadrilateral is a parallelogram? true or false

Answer 1

Look at some parallelograms of different dimensions and see if the diagonals are always perpendicular. Then you should be able to answer the question yourself. The key word in the problem is "always."

Answer 2

Hint: they do always bisect each other. Now the question is, are they "always" perpendicular?
