Read each question carefully and follow the instructions to enlarge the figures and answer the questions about scale factors and properties of transformations.

1. Plot the vertices of triangle ABC: A(1, 1), B(3, 1), C(1, 3). Then, enlarge triangle ABC by a scale factor of 2 about the origin (0,0) to create triangle A'B'C'. Plot the new vertices and state their coordinates.

A' = ( , )

B' = ( , )

C' = ( , )

2. A rectangle has vertices at (2, 2), (6, 2), (6, 4), and (2, 4). After an enlargement, the new vertices are (4, 4), (12, 4), (12, 8), and (4, 8). The scale factor of this enlargement is .

3. If a line segment with length 5 cm is enlarged to a length of 20 cm, the scale factor is .

4. Which of the following properties are preserved during an enlargement transformation?

Side lengths

Angle measures

Area

Perimeter

5. An enlargement always makes a figure bigger.

True

False

6. A photograph is 4 inches wide and 6 inches long. If it is enlarged by a scale factor of 3, what are the new dimensions of the photograph?
