Triangle DEF was dilated according to the rule DO,One-third(x,y)(one-third x, one-third y) to create similar triangle D'E'F'. On a coordinate plane, (0, 0) is the center of dilation. Triangle FDE is dilated to create smaller triangle F prime D prime E prime. Triangle FDE has points (- 9, 3), (- 9, 9), (- 6, 6). Triangle F prime D prime E prime has points (- 3, 1), (- 3, 3), and (- 2, 2). Which statements are true?A. ∠F corresponds to ∠F'. B. Segment EE' is parallel to segment FF'. C. The distance from point D' to the origin is One-third the distance of point D to the origin. D. The measure of ∠E' is One-third the measure of ∠E. E. △DEF △D'E'F'.

Ответ:
a) True.
b) False.
c) True.
d) False.
e) True.
Step-by-step explanation:
A. ∠F corresponds to ∠F'. True.
B. Segment EE' is parallel to segment FF'. False. They intersect each other at the origin.
C. The distance from point D' to the origin is One-third the distance of point D to the origin. True.
We can get the ratio D'E'/DE:
D. The measure of ∠E' is One-third the measure of ∠E. False.
E. △DEF ~ △D'E'F'. True. They are similar triangles.
