Final answer:
The dimension of the new scaled copy of the polygon using a scale factor of 1/2 is 1/4 the size of the original.
Step-by-step explanation:
The dimension of the new scaled copy of the polygon using a scale factor of 1/2 is 1/4 the size of the original. When the scale factor is 1/2, it means that the new dimensions will be half the size of the original dimensions.
Therefore, if the original polygon has dimensions of x, the scaled copy will have dimensions of 1/2*x, which is equivalent to 1/4 the size of the original.
