Given figure ABDC is a rectangle which of the work shown below could be used to verify analytically that the diagonals would bisect one another? Slope AD= (1-2) (4-(-4)) == Slope BC- Slope AC=-==-2 (-2-(-4)) (5-1) Slope DB-----2 (2-4) Slope AB= 15-2) Q-(44)) Slope CD (1-(-21) (4-(-21) Midpoint AD- (1)-(0.1.5) Midpoint BC- (25) - (0.1.5) Midpoint AB= (4)-(-1.3.5) Midpoint CD-()= (1.-0.5) Midpoint AC= (4)-(-3,0) A B D 4 2 -1 3 4 C
