Question

7. In the given figure, PQRS is a parallelogram,
whose diagonals PR and SQ intersect at O. If OR
= 7.5 cm and SQ is 5 cm less than PR, find OS.​

Answer 1

Answer:

5cm

Step-by-step explanation:

Since in parallelograms the diagonals bisect each other, if OR = 7.5 then OP  will also be 7.5. Therefore, PR = 7.5 + 7.5 = 15cm

Since SQ= PR-5, SQ = 15-5 = 10cm

10cm /2 = OQ =OS= 5cm
