Vertical and Horizontal Stretch and Shrink

Vertical and Horizontal Stretch and Shrink

Read each question carefully and follow the instructions to complete the transformations.

1. Which transformation changes the size of a figure but not its shape?

2. A horizontal stretch by a factor of 2 means that the x-coordinates are multiplied by:

3. A vertical stretch makes a figure appear  , while a vertical shrink makes it appear  .

4. When you apply a horizontal shrink, the x-coordinates are multiplied by a factor between   and  .

5. Consider a rectangle with vertices at (1,1), (3,1), (3,2), and (1,2). Draw the original rectangle and then draw the rectangle after a vertical stretch by a factor of 3. Label both figures.

6. Consider a triangle with vertices at (2,2), (6,2), and (4,5). Draw the original triangle and then draw the triangle after a horizontal shrink by a factor of 1/2. Label both figures.

7. A vertical stretch only affects the y-coordinates of a figure.

8. A horizontal shrink makes a figure wider.

9. A square has vertices at (0,0), (2,0), (2,2), and (0,2). If it undergoes a vertical shrink by a factor of 1/2 and a horizontal stretch by a factor of 3, what are the new coordinates of its vertices?
