Which statements must be true about the reflection of δxyz across ? check all that apply. m∠x'z'y' = 90° m∠mcy = 90° xx' ≅ yy' bz' ≅ bz zz' || yy' xy || x'y'

abde or 1,2,4, 5 is the answer

step-by-step explanation:

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)
