Question

There of the ABCD are given. fine the coordinates of point D. A(3, 6) B(6,3) D(x, y)

Answer 1

A. (3,2) . I recommend using desmos to find the coordinates

Answer 2

9514 1404 393

Answer:

A. (3, 2)

Explanation:

The midpoints of the diagonals are the same point, so you have ...

X = (A +C)/2 = (B +D)/2

A +C = B +D . . . . . . . multiply by 2

A +C -B = D . . . . . . . subtract B

The coordinates of D are ...

D = (3, 6) +(6, 3) -(6, 7) = (3+6-6, 6+3-7)

D = (3, 2)
