Step-by-step explanation:

Answer:

We know that by section formula, the co-ordinates of the points which divide internally the line segment joining the points (x

1

,y

1

) and (x

2

,y

2

) in the ratio m:n is

(x,y)=(

m+n

mx

2

+nx

,

m+n

my

+ny

)

O is the midpoint of AC and BD

∴(2,−5)= mid point of AC

(2,−5)=(

+2

)

2

x

+3

=2

⇒x

+3=4

∴x

=1

Also,

2

y

+2

=−5

y

+2=−10

y

1

=−12

∴c=(1,−12)

(2,−5)= Mid point of BD

(2,−5)=(

2

−1+x

,

2

0+y

)

⇒

2

−1+x

2

=2

⇒−1+x

2

=4

∴x

2

=5

⇒

2

0+y

2

=−5

∴y

2

=−10

∴D=(5,−10)
