Acute triangle ABC is rotated about a point and then dilated by a scale factor of 1/2 to produce A'B'C'. What statement correctly compared triangle A'B'C' to triangle ABC?

The angle measures and side lengths of triangle A’B’C’ are half the size of those of triangle ABC

The angle measures of triangle A’B’C’ are the same as those of triangle ABC, but the side lengths of A’B’C’ are half the size of those of triangle ABC

The angle measures of A’B’C’ are the same as those of triangle ABC, but the lengths of A’B’C’ are twice the size of those of ABC

OR

The angle measures of A’B’C’ depend on the angle of rotation, but the side lengths of A’B’C are half the size of those of ABC
