Final answer:
To find the length of A'B' in a dilation with a scale factor of 1/2, multiply the length of AB by the scale factor. A'B' = AB * (1/2).
Step-by-step explanation:
To find the length of A'B' in a dilation with a scale factor of 1/2, we need to multiply the length of AB by the scale factor. Since A'B' is dilated from AB, and AB is the original length, we can use the formula:
A'B' = AB * scale factor
So, if AB = x units, then A'B' = (x)*(1/2) = x/2 units.
