'Given figure ABCD is a rhombus which of the work shown below most directly verifies analytically that the opposite sides are parallel?
(2-6) a) Slope AC = 7-741 Slope BD = 02-0 (6-3)
(6 -0} Slope AB = 3272)
02-2) Slope CD = (6- 1)
b) Midpoint AB = 4,9)-(05,6) Midpoint CD= #4)-(35,2) Midpoint AC = #)= (-05.4) Midpoint BD = 3+6 2+6 )- (4.5,4)
c) Midpoint AD= (44,4)= (24) Midpoint BC = (4,)-(2.4)
d) (2-6) Slope AD = 7-7-211 8
0-6} Slope BC = 0173; =4-2'
