Scale Factor Practice

Front

What is the scale factor from a smaller shape to a larger shape?

Back

The scale factor is the ratio of the lengths of corresponding sides of two similar figures. It indicates how much larger or smaller one figure is compared to another.

Front

Define Scale Factor.

Back

Scale Factor is the number you multiply by the sides of a shape to create a similar figure.

Front

If the scale factor from triangle ABC to triangle DEF is 2/1, what does this mean?

Back

This means that triangle DEF is twice as large as triangle ABC.

Front

What is the scale factor from triangle DEF to triangle ABC if the scale factor from ABC to DEF is 2/1?

Back

The scale factor from DEF to ABC is 1/2.

Front

How do you find the scale factor between two similar figures?

Back

To find the scale factor, divide the length of a side of the larger figure by the length of the corresponding side of the smaller figure.

Front

If the scale factor is 3/2, what does this indicate about the two figures?

Back

This indicates that the larger figure is 1.5 times the size of the smaller figure.

Front

What is the scale factor from ABCD to MNOP if the lengths of corresponding sides are in the ratio 2:3?

Back

The scale factor is 2/3.

Front

If a shape is enlarged by a scale factor of 2, what happens to its area?

Back

The area of the shape increases by a factor of 2^2, which is 4 times larger.

Front

What happens to the perimeter of a shape if it is reduced by a scale factor of 1/2?

Back

The perimeter of the shape is also reduced by the same scale factor, becoming half of the original perimeter.

Front

If the scale factor is 1/2, how does this affect the dimensions of the shape?

Back

All dimensions of the shape are halved.
