Question

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

Explanation:

Step1: Recall scale - copy concept

A scale - copy of a shape has the same shape but a different size. The ratio of corresponding side - lengths in a scale - copy is constant. For a rectangle (assuming the shapes are rectangles), a vertical slider (Shape A) will change the height but not maintain the same shape ratio if the width doesn't change proportionally. A horizontal slider (Shape B) can change the length of the rectangle while maintaining the same shape (since the height remains constant and the length changes uniformly), creating scale copies.

Answer:

B. Slider for Shape B
