Look at the coordinates given in Part 2. If you were to translate this figure 10 units down, how would you find the new coordinates?
Subtract 10 from each y-coordinate.
If you were dilate this figure by a factor of 4, how would you find the new coordinates?
Multiply the
What type of transformation is shown in Part 3?
A 90º clockwise rotation, or a 270º counterclockwise rotation.
Are these 2 triangles congruent? How do you know?
Yes. After a rotation, the image is congruent to the pre-image.
