Answer:
A scaled copy is a copy of an figure where every length in the original figure is multiplied by the same number.
The original figure A is 2 units wide and 2 units high. The scaled copies must follow the same ratio of width to height (2 : 2), as well as the vertices of the figure remaining the same.
Therefore, figures 2 and 4 are scaled copies only.
No, for figure B to be a scaled copy, the width would also have to be scaled down. As the width has remained the same in both figures, figure B is not a scaled copy.
A & D are scaled copies
