Question

Diagonals of a quadrilateral PQRS bisect each other. If < PQ = 450 , determine ​

Answer 1

Step-by-step explanation:

The diagonals of a quadrilateral bisect at right angles. Since, the diagonal bisect each other hence, the quadrilateral is a parallelogram.

The diagonals of the quadrilateral bisect at right angles, hence it is a square.

Now, all the sides of the square are equal and perimeter = 4S=4×5.5=22 cm
