Scale Factors Cont.

Front

If a copy has a scale factor of 1/2, what does this mean?

Back

The copy is smaller than the original.

Front

What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, some quantity. It determines how much larger or smaller a figure is compared to the original.

Front

If the scale factor is 2, how does the size of the copy compare to the original?

Back

The copy is bigger than the original.

Front

What does a scale factor of 1 indicate?

Back

A scale factor of 1 means the copy is the same size as the original.

Front

If the original length is 36mm and the scale factor is 1/2, what is the length of the copy?

Back

18mm.

Front

In a scaled copy, if side length HJ corresponds to side length AB, what can we say about their relationship?

Back

They are proportional based on the scale factor.

Front

What is the relationship between the original figure and the scaled figure when the scale factor is less than 1?

Back

The scaled figure is a reduction of the original figure.

Front

If a figure is scaled by a factor of 1/4, what happens to its area?

Back

The area of the figure is reduced to 1/16 of the original area.

Front

How do you find the corresponding side length in a scaled figure?

Back

Multiply the original side length by the scale factor.

Front

If the scale factor is 3, what happens to the dimensions of the original figure?

Back

All dimensions are tripled.
