26) Answer is choice A: y = -3
This is the horizontal line that cuts the figure into two congruent pieces.

27) Answer is choice A: AB = 24 and DE = 12
CA/DF = 12/6 = 2
CB/FE = 20/10 = 2
The ratio of the larger to smaller corresponding sides is 2:1 or just 2
So AB needs to be twice as long as DE
That only happens with choice A
