Solution

The correct option is C Angle A = Angle A'
Here, A'B'C' is obtained by rotating ABC by 120 degrees. Since C is at the center of rotation, the rotation leaves its coordinates unchanged.

Therefore, the coordinates of C and C' remain the same.

Perimeters of ABC and A'B'C' remain the same as rotation does not affect their perimeters.

The angle measure does not change after rotation, so angle A is equal to angle A'.

Therefore, option (c) is the correct answer.
