The property which is always true for a parallelogram is A. diagonals bisect each other.
Quadrilateral:
The quadrilaterals which has opposite sides equal and parallel are known as parallelogram.
one of the properties of parallelogram is its both diagonals bisect each other.
Parallelogram:
Parallelogram has many types like rectangle, square, rhombus etc.
These parallelogram has some special properties like square is a parallelogram which has all four sides equal, but this is not the case in rectangle.
In rectangle only opposite pair of sides are equal. Similarly in rhombus, all four sides are equal but its diagonals perpendicularly bisect each other.
Hence from the above explanation we find that only rhombus has the diagonals which are perpendicular and bisect each other while in all the other parallelograms the diagonals bisect each other.
But in all parallelogram one property is common which is its diagonal bisect each other.
So, we say that the diagonal of parallelogram always bisect each other is always true.
Hence the correct option is A.Diagonals bisect each other.
