drag the sliders. which slider creates scale copies of the shape? choose 1 answer: a slider for shape a b…

Explanation:

Step1: Understand scale copies

Scale copies have proportional side - lengths.

Step2: Analyze Shape A

Shape A is a vertical rectangle. If we change its size using a slider, the ratio of its height to width (which is very large initially) will not remain the same for non - scale factor changes.

Step3: Analyze Shape B

Shape B is a rectangle. When we use a slider to change its size, if it is a scale copy, the ratio of its length to width remains the same. For a rectangle (a more "balanced" shape compared to the very tall Shape A), when we scale it (multiply both length and width by the same factor), it remains a rectangle (a scale copy).

Answer:

B. Slider for Shape B
