Dilations and scale factors

Front

What happens to a figure when the scale factor is less than one?

Back

The figure undergoes a reduction.

Front

What is the scale factor when comparing two similar triangles, ΔDEF and ΔABC, if ΔABC is twice the size of ΔDEF?

Back

The scale factor is 2.

Front

What is an example of a scale factor that indicates an enlargement?

Back

A scale factor of 2.5 indicates an enlargement.

Front

If a small shape is scaled to a big shape with a scale factor of 2, what does this mean?

Back

The dimensions of the small shape are doubled to create the big shape.

Front

In the algebraic transformation from (x,y) to (2x,2y), what is the scale factor?

Back

The scale factor k is 2.

Front

Define scale factor in the context of dilations.

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

Front

What is the effect of a scale factor greater than one on a geometric figure?

Back

The figure is enlarged.

Front

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

Back

Divide the length of a side of the larger figure by the corresponding side of the smaller figure.

Front

What is the scale factor if a triangle's side lengths are multiplied by 3?

Back

The scale factor is 3.

Front

If a figure is dilated with a scale factor of 0.5, what is the relationship between the original and the new figure?

Back

The new figure is half the size of the original figure.
