Answer:
Angles are the same, So:
C = G = 125
H = D = 75
A = E = 360 - ( 90+75+125) = 70
To know the ratio between the lengths. Divide 6 by 9 so you get 2/3
So every side of small polygon equals 2/3 times side of big polygon. ( THE PARALLEL ONES )
So:
FG = 7* 2/3 = 14/3
GH = 11 * 2/3 = 22/3
EH = 12 * 2/3 = 8
