Question

plzzz do solve this math problem...​

Answer 1

Answer:

The value of os =5cm and OR=3cm because opposite side are divided in equal parts

Answer 2

Question given :

• We are given with a parallelogram that is PQRS and it has two diagonals that are OS and PR
• A point O intersects the both diagonals and divide them into two equal halves

Given parameters :

• QS = 10 cm
• OR = 3 cm

To find :

• The length of OS
• The length of PR

Required solution :

We know that the point O of intersection divides the both diagonals into two equal halves hence we know that ,

• $\sf\implies\:OR\:=\:OP$
• $\sf\implies\:OR\:+\:OP\:=\:PR$
• $\sf\implies\:QO\:=\:OS$
• $\sf\implies\:QO\:+\:OS\:=\:QS$

So therefore ,

• $\sf\implies\:OR\:+\:OP\:=\:PR$
• $\sf\implies\:3\:cm\:+\:3\:cm\:=\:PR$
• $\sf\implies\:6\:cm\:=\:PR$

And also ,

• $\sf\implies\:QO\:+\:OS\:=\:QS$
• $\sf\implies\:2OS\:=\:10\:cm$
• $\sf\implies\:OS\:=\:\dfrac{10}{2}$
• $\sf\implies\:OS\:=\:5\:cm$
