Triangle ABC has vertices A(−2, 0), B(2, 5), C(3, 1). The reflection of the image of triangle ABC is triangle A'B' C' with vertices A'(−2, 0), B'(2, −5), C'(3, −1). What is a rule that describes the reflection?

e) none of the above because the measure of angle cba is 101°

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)
