प्रश्न
State, 'true' or 'false'
Every parallelogram is a rhombus.
पर्याय
True
False
उत्तर
False
This is false since a parallelogram, in general, does not have all its sides equal. Only the opposite sides of a parallelogram are equal. However, a rhombus has all its sides equal. So, every parallelogram cannot be a rhombus, except those parallelograms that have all equal sides.
