Question

Example 10: If the points A(6, 1), B(8, 2), C(9, 4) and D(p), 3) are the vertices o
parallelogram, taken in order, find the value of p. by section formula ​

Answer 1

Answer:

We know that the diagonals of a parallelogram bisect each other. So, coordinates of the mid-point of diagonal AC are same as the coordinates of the mid-point of diagonal BD.

∴(26+9,21+4)=(28+p,22+3)

⇒(215,25)=(28+p,25)

⇒215=28+p⇒15=8+p⇒p=7
