A B C D is a parallelogram whose diag...

`A B C D` is a parallelogram whose diagonals intersect at `Odot` If `P` is any point on `B O ,` prove that: `a r\ ( A D O)=A R\ ( C D O)` `a r\ (\ A B P)=\ a r\ (\ C B P)`

Text Solution

Verified by Experts

Proof :
`AC` is the diagonal of the parallelogram.
∴ `AO = OC` [Diagonal of a parallelogram bisect each other]
`O` is the midpoint of `AC` Þ `DO` is the median.
