Look at this for all you need to know about parallelograms and their diagonals. http://www.wyzant.com/resources/lessons/math/geometry/quadrilaterals/properties_of_parallelograms

They are not perpendicular...here it will tell you why.  There are only two things about the diagonals of parallelograms that are always true.

imstuck · Answer

If a quadrilateral is a parallelogram, then.

(1) its diagonals bisect each other, and

(2) each diagonal splits the parallelogram into two congruent triangles.

those are the only 2 things about diagonals that are a for-sure thing.
