Scale Factor

Front

What is the scale factor?

Back

The 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 the original.

Front

If the scale factor is less than one, what does it indicate about the new figure?

Back

It indicates that the new figure is a reduction of the original figure.

Front

What does a scale factor greater than one indicate?

Back

It indicates that the new figure is an enlargement of the original figure.

Front

How do you determine if two figures are similar?

Back

Two figures are similar if their corresponding angles are equal and the lengths of their corresponding sides are proportional.

Front

What is a scaled copy?

Back

A scaled copy is a figure that has been enlarged or reduced by a scale factor, maintaining the same shape as the original.

Front

If a triangle has a scale factor of 1/2, what happens to its size?

Back

The triangle will be reduced to half its original size.

Front

What is the relationship between scale factor and area?

Back

If the scale factor is k, the area of the new figure is k² times the area of the original figure.

Front

What is the scale factor if a rectangle's length is doubled and width remains the same?

Back

The scale factor is 2 for the length, and the overall scale factor is determined by both dimensions.

Front

If a figure is enlarged by a scale factor of 3, what happens to its dimensions?

Back

Each dimension of the figure is multiplied by 3.

Front

What is the formula to find the scale factor between two similar figures?

Back

Scale Factor = Length of Side in New Figure / Length of Corresponding Side in Original Figure.
