The figure shows a quadrilateral PQRS having equal sides and opposite sides parallel. The diagonals PR and QS intersect perpendicularly at O, Which of the following statements cannot be correct
- |PO|=|RO|
-
PQR is an equilateral triangle
- PQRX is a parallelogram
- There are two lines of symmetry
The correct answer is: B
Explanation
Since PQRS is a quadrilateral with equal sides, PQR cannot be an equilateral triangle unless R coincides with S, which is not the case in a quadrilateral.
