Front

If a figure is dilated by a scale factor of 2, what happens to its dimensions?

Back

Each dimension of the figure is multiplied by 2, resulting in an enlarged figure.

Front

What is the relationship between the original figure and the dilated figure?

Back

The original figure and the dilated figure are similar, meaning they have the same shape but different sizes.

Front

How do you determine the scale factor from the original and dilated dimensions?

Back

Divide the dimension of the dilated figure by the corresponding dimension of the original figure.
