How can you tell by looking at the coordinates of the two triangles that AA'B'C' is a 180° rotation of A ABC? A)
The coordinates cannot prove a 180° rotation.
B)
The y-coordinates of the points on AA'B'C' have opposite signs from the
corresponding points on AABC.
The x-coordinates of the points on AA'B'C' have opposite signs from the
corresponding points on AABC.
Both the x and y coordinates of the points on AA'B'C' have opposite signs
from the corresponding points on AABC.
D)
