Similarity Transformations Worksheet with Answer Key

What's on the worksheet

1. Find the unknown scale factor in a sequence of dilations and a reflection.
2. Find the scale factor from a school banner design to a larger one.
3. Write a single rule for each sequence and give its scale factor:
   Reflect in the line y = x, then dilate by \dfrac12.Dilate by 4, then translate by \langle -1, 3 \rangle.Translate by \langle 2, -1 \rangle, then dilate by 3.Dilate by 2, rotate 90° clockwise, then dilate by \dfrac32.
4. Decide if pizza slices cut as sectors of circles are similar.
5. Find the image of a square under a slant tool and decide if it is a similarity.
6. Break a single rule into a dilation and a rotation and find its center.
7. Reflect and dilate a trapezoid and describe what is preserved.
