1. Which of the following statements is true about scaled copies?
Angles are multiplied by the scale factor.
Side lengths are always equal to the original.
Corresponding angles remain the same.
The shape changes, but not the size.
2. If a rectangle with side lengths 4 cm and 6 cm is scaled by a factor of 2, what are the new side lengths?
6 cm and 8 cm
8 cm and 12 cm
