1. Triangle ABC has side lengths AB = 3 cm, BC = 4 cm, and AC = 5 cm. If triangle DEF is a scaled copy of triangle ABC with a scale factor of 2.5, what are the side lengths of triangle DEF?

2. A photograph measures 4 inches by 6 inches. If it is enlarged to a scaled copy that is 10 inches wide, what is the new length of the photograph?

3. Which of the following statements is true about scaled copies?

Angles change proportionally in a scaled copy.

Side lengths are always equal in a scaled copy.

Corresponding angles remain the same in a scaled copy.

Scaled copies always have a scale factor greater than 1.

4. Consider a rectangle with a length of 8 units and a width of 4 units. Draw a scaled copy of this rectangle with a scale factor of 0.5. Label the dimensions of the new rectangle.

5. A circle has a radius of 6 cm. If you create a scaled copy of this circle with a scale factor of 3, what will be the circumference of the new circle? (Use π ≈ 3.14)
