Looks like you'll have to do all of the calculations mentioned below:
A: midpoint between A&C is (4,6)
B:midpoint between D&C is (-6,3)
C:midpoint between A&B is (-3/2,5)
D: midpoint between B&D is (-9,3)
until you find one that is true.
For example: Find the midpoint of the line segment AC. This midpoint is
(-6+2, 10-4)/2, or (-4, 6)/2, or (-2,3). Thus, answer choice A is FALSE.
Please continue. Find the midpoint of line segment CD yourself and then compare your result to (-6,3). Is your result the same or different?
And so on.
