Scale factor flashcard.

Front

What is the scale factor?

Back

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

Front

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

Back

It means the copy is smaller than the original.

Front

What does it mean to reduce a figure?

Back

To reduce a figure means to make it smaller while maintaining its proportions.

Front

What is an enlargement in terms of scale factor?

Back

An enlargement occurs when the scale factor is greater than 1, making the figure larger than the original.

Front

What is a scale drawing?

Back

A scale drawing is a representation of an object that is proportional to the actual object, using a specific scale factor.

Front

If the scale factor is 2, how does the new figure compare to the original?

Back

The new figure is twice as large as the original.

Front

What happens to the dimensions of a figure if the scale factor is 1?

Back

If the scale factor is 1, the dimensions of the figure remain the same as the original.

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 new figure by the length of the corresponding side of the original figure.

Front

What is the scale factor if a figure is enlarged from 3 cm to 9 cm?

Back

The scale factor is 3 (9 cm ÷ 3 cm = 3).

What does it mean if two figures are not proportional?

Back

It means that the figures do not have the same shape or their corresponding sides are not in the same ratio.
