A parallelogram is a rhombus if and only if the diagonals are perpendicular
A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle or square. A parallelogram without perpendicular sides is a rhomboid or rhombus.
The single altitude of a parallelogram is its perpendicular height
if the diagonals of parallelogram become Perpendicular then the figure is said to be rhombus......
The area of a parallelogram with base 18cm and perpendicular height 18cm is 324 cm2
A parallelogram with perpendicular sides is called a rectangle.
no it does not
Yes, if the parallelogram is a rhombus or a square.
By definition, a parallelogram two separate pairs has parallel sides. The only type of parallelogram that has perpendicular sides is a rectangle. All others have non-perpendicular sides.

A rhombus
rhombus
No. Not necessarily.
Generally no. If they are perpendicular, all four angles are right angles and the parallelogram is usually called a rectangle.
