Question

label: scale
scale factor
scale down
scale up
scale drawing
1.______
2.______
3.______
4.______

Explanation:

Step1: Define scale - factor

The ratio of the corresponding side - lengths of two similar figures. Here, the ratio of the side - lengths of the larger to the smaller diamond is $2:1$, so the scale factor is $\frac{2}{1}=2$.

Step2: Define scale - down

Scale - down means reducing the size of a figure. In this case, going from the larger diamond to the smaller diamond is a scale - down.

Step3: Define scale - up

Scale - up means increasing the size of a figure. If we were going from the smaller diamond to the larger diamond, it would be a scale - up.

Step4: Define scale - drawing

A scale drawing is a drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (the scale factor).

Answer:

1. 2
2. Going from the larger diamond to the smaller diamond
3. Going from the smaller diamond to the larger diamond
4. A drawing that shows a real object with accurate sizes reduced or enlarged by a certain amount (the scale factor)
