Question

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

Explanation:

Step1: Understand scale copies

A scale copy of a shape has all corresponding sides in proportion. Shape A is a rectangle. If we change its dimensions using a slider, if it's a scale - copy slider, the ratio of length to width remains the same.

Step2: Analyze Shape B

Shape B is a square (assuming from its appearance). A square has equal length and width. If we drag its slider, since length and width are equal, any scaling (increase or decrease) will keep it as a square (a special case of a rectangle with length = width). For a rectangle (Shape A), if the slider is for non - scale changes (e.g., changing length without changing width proportionally), it won't be a scale copy. But for a square (Shape B), when we drag its slider (assuming uniform scaling), the ratio of side lengths (which is 1:1) remains the same.

Answer:

B. Slider for Shape B
