Dilations and Scale Factor Practice

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but not its shape, using a scale factor.

Front

What does a scale factor greater than 1 indicate?

Back

A scale factor greater than 1 indicates an enlargement of the figure.

Front

What does a scale factor less than 1 indicate?

Back

A scale factor less than 1 indicates a reduction of the figure.

Front

If a figure is dilated by a scale factor of 1, what happens to the figure?

Back

The figure remains unchanged.

Front

How do you determine if a dilation is an enlargement or a reduction?

Back

If the scale factor is greater than 1, it is an enlargement; if it is less than 1, it is a reduction.

Front

What is the scale factor if a triangle with sides 3, 4, and 5 is dilated to sides 6, 8, and 10?

Back

The scale factor is 2.

Front

If a rectangle is dilated by a scale factor of 1/2, what happens to its area?

Back

The area of the rectangle is reduced to 1/4 of its original area.

Front

What is the formula to find the new length after dilation?

Back

New Length = Original Length × Scale Factor.

Front

If a shape is reduced by a scale factor of 3/5, what is the relationship between the original and new dimensions?

Back

The new dimensions are 3/5 of the original dimensions.

Front

What is the effect of a scale factor of 0 on a figure?

Back

A scale factor of 0 reduces the figure to a point.
