Question

17. PQRS is a quadrilateral, PR and QS
intersect each other at O. In which of the
following cases, PQRS is a parallelogram?
ZP = 100°, ZQ = 80°, R = 100°
<P =85°, ZQ = 85°, ZR = 95°
PQ = 7 cm, QR = 7 cm, RS = 8 cm, SP = 8
cm
OP = 6.5 cm, OQ = 6.5 cm, OR = 5.2 cm,
OS = 5.2 cm​

Answer 1

The last option is the actual parallelogram because in parallelogram both the diagonals are equal.
