Unit Two: Dilations

Front

What is a dilation in geometry?

Back

A dilation is a transformation that alters the size of a figure but preserves its shape.

Front

What happens to a figure when a scale factor greater than 1 is applied?

Back

The figure enlarges.

Front

What happens to a figure when a scale factor between 0 and 1 is applied?

Back

The figure reduces in size.

Front

What is the scale factor in a dilation?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

Front

Which scale factor will produce an enlargement?

Back

A scale factor greater than 1, such as 5.

Front

What type of transformation is a dilation?

Back

Dilation is a type of transformation that enlarges or shrinks a shape.

Front

What is the dilation rule for enlarging a shape?

Back

Front

What is the dilation rule for reducing a shape?

Back

Front

If a figure is dilated by a scale factor of 2, what is the new coordinate of the point (3,4)?

Back

The new coordinate will be (6,8).

Front

What does it mean for a figure to be preserved during a dilation?

Back

It means the shape and angles remain the same, but the size may change.
