Question

The coordinates of rectangle ABCD are A(2, -7), B(8, -7), C(8, -10), D(2, -10). What are the coordinates of the point of intersection of the diagonals of the rectangle after the rectangle is reflected across the x -axis?

Answer 1

(-5, -8.5)

(5, 8.5)

(5, -8.5)

(-5, 8.5)

Answer 2

the original diagonal coordinate minus the height

Answer 3

huh what is the original diagonal ?

Answer 4

diagonals of a rectangle bisect each other.
point of intersection of diagonals=mid point of AC={(2+8)/2 ,(-7-10)/2}=(5,-17/2)
Its reflection on X-axis=(5,17/2)

Answer 5

its reflection on X-axis=(5,8.5)

Answer 6

Thank you :D
