1 Wkst Reflections & Translations Name Geometry Regular Date Mod Score out of 4 Tell whether each figure appears to be a reflection or translation. If it is neither, write none Reflect the figure with the given vertices across the given line

2 Translate the figure with the given vertices along the given vector Leigh and Derek are tossing a Frisbee. Leigh stands at (2, 5) and throws the disc to Derek at (11, 0). Find the translation vector from Leigh to Derek. 20. Bob the builder is trying to level out some dirt. He picks up some excess dirt at (9, 16) and maneuvers through the job site along the vectors -6, 0, 2, 5, and 8, 10 to get to the spot to unload the dirt. Find the coordinates of the unloading point. Find a single vector from the loading point to the unloading point.

3 Wkst 9.3 & 9.6 Rotations & Dilations Name Geometry Regular Date Mod Score out of 4 Tell whether each figure appears to be a rotation or dilation. If it is neither, write none Rotate the figure with the given vertices about the origin with the given angle of rotation

4 Draw the image of the figure with the given vertices under a dilation with the given scale factor centered at the origin A sign painter creates a rectangular sign for Hermey s Dentist Office on his computer desktop. The desktop version is 12 inches by 4 inches. The actual sign will be 15 feet by 5 feet. If the capital H in Hermey s will be 4 feet tall, find the height of the H on his desktop version.

5 WS 9.4 Compositions of Transformations Name Geometry Regular Date Mod Score out of 4 Draw the result of each composition of transformations

6 Each of the following is a face of the cube shown below. In the space to its right, make a sketch of the face of the cube that is directly opposite the given face. a. b.

7 Worksheet 9.5 Symmetry Name Geometry Regular Date Mod Score out of 4 Tell whether each figure has line symmetry. If so, draw all lines of symmetry Tell whether each figure has rotational symmetry. If so, give the angle of rotational symmetry and the order of symmetry

8 Tell whether each figure has plane symmetry, symmetry about an axis, both, or neither Draw all lines of symmetry for each name if possible.

9 Worksheet Transformations Geometry Regular Name Date Mod What would happen to the figures below if they were reflected across two vertical lines? Perform the transformation to find out. Now reflect your drawing across line l. l Describe the images you drew after reflecting over the two vertical lines. Is there another transformation that will produce the same images in one step? Describe the images you drew after reflecting over line l.

10 Draw a 90 rotation and a horizontal reflection of each image. Decide whether each transformation is rotation, reflection, or translation.

11 Look at the figure in the far left column. Then find and circle the figure (a, b, or c) that is congruent to the first. Was the congruent figure reflected, rotated, or translated? The shaded figure can be rotated different ways. Shade the other figures to show how the first can be rotated. What transformation can you perform to show that the two figures are congruent?

12 Which of the capital letters below can be reflected across a vertical line and still look the same? Circle them. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Examine the regular pentagon below. Suppose it undergoes a dilation with a scale factor of 4.5 a. How long is each side of the new image? b. Are the two images similar? Justify your answer. c. Do you think all dilations produce similar figures? Why or Why not? Graph the coordinates in the first column. Translate the images by graphing the coordinates in the second and third columns. Write a translation vector that will allow you to translate from the first image to the third image. Translation vector Use the space below to draw a SCHOOL-APPROPRIATE image. Find a partner and have him or her reflect that image across a vertical line.
