Which statements are true about the parallelograms? Select three options. The length of side MN is 2 units. The length of side \( M^{\prime} N^{\prime} \) is 5 units. The image is smaller than the pre-image. The scale factor is \( \frac{2}{5} \).

Step-by-step Solution
To determine which statements are true about the parallelograms, we need to analyze the relationships between the sides and the scale factor.
1. **The length of side MN is 2 units.** - This statement could be true if it is given or can be derived from the context.
2. **The length of side \( M^{\prime} N^{\prime} \) is 5 units.** - This statement could also be true if it is given or can be derived from the context.
3. **The image is smaller than the pre-image.** - This statement is true if the scale factor is less than 1.
4. **The scale factor is \( \frac{2}{5} \).** - This scale factor indicates that the image is smaller than the pre-image, as \( \frac{2}{5} < 1 \).
Assuming the first two statements are true (that MN is 2 units and \( M^{\prime} N^{\prime} \) is 5 units), we can calculate the scale factor:
\[
\text{Scale Factor} = \frac{\text{Length of image}}{\text{Length of pre-image}} = \frac{2}{5}
\]
This confirms that the scale factor is indeed \( \frac{2}{5} \), and since this is less than 1, the image is smaller than the pre-image.
Thus, the three true statements about the parallelograms are:
1. The length of side MN is 2 units.
2. The length of side \( M^{\prime} N^{\prime} \) is 5 units.
3. The image is smaller than the pre-image.
The scale factor being \( \frac{2}{5} \) is also true, but since we need to select three options, we can conclude that the first three statements are the ones to choose.
Quick Answer
1. The length of side MN is 2 units.
2. The length of side \( M^{\prime} N^{\prime} \) is 5 units.
3. The image is smaller than the pre-image.
