To determine whether a dilation is an enlargement or a reduction based on the scale factor, we can use the following rules:
- If the scale factor is greater than 1, the dilation is an enlargement.
- If the scale factor is less than 1 (but greater than 0), the dilation is a reduction.
Now let's analyze the responses:
-
AB is an enlargement of A′B′ by a scale factor of 2.
- Scale factor: 2 (greater than 1) ➔ This is an enlargement.
-
AB is a reduction of A′B′ by a scale factor of 12.
- Scale factor: 12 (greater than 1) ➔ This statement is incorrect because it states a reduction with a scale factor greater than 1.
-
A′B′ is an enlargement of AB by a scale factor of 2.
- Scale factor: 2 (greater than 1) ➔ This is an enlargement.
-
A′B′ is a reduction of AB by a scale factor of 12.
- Scale factor: 12 (greater than 1) ➔ This statement is incorrect because it states a reduction with a scale factor greater than 1.
-
AB is a reduction of A′B′ by a scale factor of 1/2.
- Scale factor: 1/2 (less than 1) ➔ This is a reduction.
-
A′B′ is a reduction of AB by a scale factor of 1/2.
- Scale factor: 1/2 (less than 1) ➔ This is a reduction.
From the analysis, the correct classifications based on the provided scale factors are:
- Enlargement (scale factor of 2)
- Enlargement (scale factor of 2)
- Reduction (scale factor of 1/2)
- Reduction (scale factor of 1/2)
The statements that are correct with their classifications are:
- Enlargement by a scale factor of 2
- Reduction by a scale factor of 1/2
The incorrect statements are those suggesting a reduction with a scale factor greater than 1.
