Answer 1

Answer:

hloo mate...

here's ur answer...

1. first draw a parallelogram ABCD.
2. Join AC (diagonal of parallelogram)
3. now u know the formula for area of triangle in coordinate geometry.
4. so according to this, area of triangle ABC wilk be equal to area of triangle ADC.
5. Equate both the equations..
6. hence u will get the coordinates of D.

hope it helps.....

Here,

As in the attached attachment...

We know that it is a parallelogram.. Then if we divide that parallelogram with its one diagonal as AC then there will be two congruent triangles are formed as triangle ABC and triangle ACD.

Therefore, the coordinates of D vertex is (x2, y2)
