Hiro is creating a smaller scaled replica of a triangular canvas. Which of the following expressions will help him determine the length of segment AB?

AC equals AD times AB over AC
AB equals AE times AD over AB
AB = AD
AB = AC

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
