Dilations & Scale Factors

Front

What is a scale factor?

Back

A scale factor is a number that scales, or multiplies, a quantity. In dilations, it determines how much larger or smaller a figure will be compared to the original.

Front

If the scale factor is 1, what happens to the figure?

Back

The figure remains the same size; it is neither enlarged nor reduced.

Front

What does it mean if the scale factor is less than 1?

Back

It means the figure will be reduced in size.

Front

What does it mean if the scale factor is greater than 1?

Back

It means the figure will be enlarged.

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but different sizes. They have proportional corresponding sides.

Front

What is the relationship between scale factors and dilations?

Back

Scale factors are used in dilations to determine how much a figure is enlarged or reduced.

Front

If a triangle has a scale factor of 2, what happens to its dimensions?

Back

Each dimension of the triangle is multiplied by 2, making it twice as large.

Front

What is a reduction dilation?

Back

A reduction dilation is when the scale factor is between 0 and 1, resulting in a smaller figure.

Front

What is an enlargement dilation?

Back

An enlargement dilation occurs when the scale factor is greater than 1, resulting in a larger figure.

Front

If a shape is dilated with a scale factor of -1, what happens?

Back

The shape is reflected over the origin and its size remains the same.
