What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, some quantity. It is used to determine how much larger or smaller a figure is compared to another figure.

Front

If the scale factor is greater than one, what happens to the figure?

Back

The figure undergoes an enlargement.

Front

What are corresponding sides?

Back

Corresponding sides are sides that are in the same position in different shapes.

Front

What does it mean if two figures are similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size, and their corresponding sides are in proportion.

Front

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

Back

To find the length of a corresponding side, multiply the length of the original side by the scale factor.

Front

What is the relationship between corresponding angles in similar figures?

Back

Corresponding angles in similar figures are equal.

Front

What is the scale factor if a side length is multiplied by 4?

Back

The scale factor is 4.

Front

If a figure is reduced by a scale factor of 0.25, what happens to its size?

Back

The figure is reduced to one-fourth of its original size.

Front

What is the term for sides that are equal in length in two figures?

Back

Congruent sides.

Front

How can you determine if two figures are proportional?

Back

Two figures are proportional if the ratios of their corresponding side lengths are equal.
