URGENT PLEASE HELP!!!!! WILL GIVE BRAINLIEST!!!
The coordinates of parallelogram ABCD are A(0, 0), B(a, 0), C(
,

), and D(0, b).

The coordinates of the midpoint of AC¯¯¯¯¯ are (

,b2).

The coordinates of the midpoint of BD¯¯¯¯¯ are (a2,

).

The midpoints of the diagonals have the same coordinates.

Therefore, AC¯¯¯¯¯ and BD¯¯¯¯¯ bisect each other.
