The diagonals of a parallelogram bisect each other.
If the diagonals of a quadrilateral bisect each other, the quadrilateral is a parallelogram.
Rectangles are parallelograms with congruent diagonals.

Respuesta :

The opposite angles are equal i) < A = <C ii) < B = < D

The opposite sides are equal that is

i)AB =CD

ii) AD= BC

The diagonals bisect each other

i) AO=OC

ii)BO=OD

What is the adjacent angle?

The adjacent angle are supplementary . that is

i)<D + < C=180 degree

ii)<A+<D=180degree

iii)<B+<C=180 degree

The opposite angles are equal i) < A = <C ii) < B = < D.
