Answer:
A will have this new coordinate (2, 1).
S will have this new coordinate (-2, 7).
E will have this new coordinate (2, 7).
Step-by-step explanation:
A is the coordinate (-1, 2).
S is the coordinate (-7, -2).
E is the coordinate (-7, 2).
To rotate that figure 270 grades (is the same to rotate 90 grades) we need to convert those coordinates to this (y, -x).
So,
A will have this new coordinate (2, 1).
S will have this new coordinate (-2, 7).
E will have this new coordinate (2, 7).
