Question

drag the sliders.
image of two rectangles (shape a: blue, longer; shape b: green, shorter) and two sliders labeled shape a and shape b
which slider creates scale copies of the shape?
choose 1 answer:
a slider for shape a
b slider for shape b

Explanation:

A scale copy of a shape maintains the same proportions (ratios of length to width, for a rectangle). Shape A is a rectangle, and adjusting its slider should scale both length and width proportionally to create a scale copy. Shape B's slider might alter the shape non - proportionally. So the slider for Shape A creates scale copies.

Answer:

A. Slider for Shape A
