Question

Prove that the points (6, 8), (3, 7), (- 2, - 2), (1, - 1) are the vertices of a parallelogram.

Answer 1

Step-by-step explanation:

To prove that the vertices are of a parallelogram we need to prove that the mid points of the diagonals have same coordinates ..let

A(6,8)

B(3,7)

C(-2,-2)

D(1,-1)

diagonals : AC&BD

mid point of AC (x1+x2)/2,(y1+y2)/2

=(2,3)

mid point of BD :(2,3)

Hence proved ..they are the vertices of a parallelogram
